It’s Karin Wanderer Learns’ birthday!

KWL is 1 year old!

1 year! 52 whole weeks! When I started this blog, I didn’t even have a title card! Now I do – in fact, I just recently designed a new one! It is a self portrait in the style of Tomie dePaola, one of my favorite illustrators.

I started this blog because I needed a place to archive all the arty things I learn. Explaining something to someone else is an easy way to reinforce your own knowledge while spotting areas that need to be explored more deeply. I chose to shout my explanations into the WriteFreely void rather than talking my friends’ & families' ears off, & I am so glad I did! (They probably are, too.) Originally I was writing articles about whatever amused me and the articles were pretty short. Things quickly grew until I was doing things like writing a whole series of longer articles about #WatercolorScience & the history of Sumi. I'm not complaining- I love learning & writing about art! I kind of have to love it to keep KWL going- no one is paying me to do this. (Though they could be!) It takes a lot of time to research things, process them, & then write about them. Part of that is definitely on me, though. I type slowly.

If you had told me a year ago that I would still be writing weekly art articles, I probably would have said “yeah, that sounds like me. This is fun & I am nothing if not a creature of habit.” Now if you had told me that I would use the 1 year anniversary to shake things up, I might not have believed you. I should have believed, though. Change is coming!

In fact, it’s already here…

Last week, I started a new art challenge: #KWPrompts, brought to you most places prompts are posted:

Mastodon Bluesky IG

The challenge is very laid-back, I’m only putting a new prompt out every other Tuesday, so you have a whole 2 weeks to participate. Or go ahead & draw something for an outdated prompt. If it makes you happy, it can’t be that bad!

“But Karin” you say “KWL comes out on Tuesdays! How will you handle writing a mind-blowingly stunning article AND a soul-rendingly heartfelt art prompt AT THE SAME TIME?!??” And that’s the best part- I don’t!

Going forward, I will be alternating between releasing either a new article or a new art prompt on Tuesdays. I’m going to have so much more time for activities! #KWPrompts was one of my New Year’s resolutions. Actually, it was 1 of 2 resolutions that related to KWL directly…

Calling All Artists!

You may have noticed that I have a nice, small section of articles on Featured Artists. I want that section to grow & grow! Lately I got sidetracked learning about brilliant author Tomie dePaola & trying to read all his books, which is a tall order- there are over 200! (Big thanks to my local library system, I could never have read dozens of dePaola books without their help!) I want to write about more artists, & maybe interview current artists instead of just researching & writing about people on my own? If there is an artist (or you are an artist) who you think should be featured, let me know on Mastodon, Ko-Fi, or BlueSky!

I posted this turtle painting a year ago, the same week I started my blog.

The last year has been fantastic! I am so happy with everything I’ve learned & I’m thrilled how many of you have come along for the ride with me. I think these changes are going to make things even more fun! I’ll be here every Tuesday to talk more about art (& sometimes cooking) or to post links to each #KWPrompts art challenge. I hope you’ll be here, too!

I posted this turtle recently. What a difference a year makes!

This blog has an ongoing series of #WatercolorScience articles about how different types of weather affect your painting, even if you work inside. Extreme Heat & low humidity: We're Having a Heat Wave & I Started This Heat Wave Freezing Temperatures: When Winter Comes Howling In Humidity & Rain: Lost in a Fog

If you want to paint en plein air (fancy art term for outside) you will need to consider the weather as well as a number of other factors. Let’s begin at the beginning.

A Super Beginner’s Guide to Painting Skillfully Outside

Painting outside is more different from painting inside than you may realize. What you bring to paint, what you bring for yourself, where you go, how you sit… Everything has to be thought out in advance. Start with figuring out what you want to bring with you & then do a test run at home. I tried out my potential art kit while sitting on my tiny porch. This helped me realize I had completely forgotten a waterproof pen & water for me to drink.

The following lists are just suggestions – I don’t carry everything on them, & sometimes I pack extra things. I don’t have a car, so generally if it won’t fit in a backpack, it doesn’t go in my kit. Luckily enough there are several parks with chairs & tables nearby, so I can skip carrying in my own furniture!

Kit For Painting

• Paper
• Waterproof pen(s)
• Brushes: sizes 2,6, & one from 99¢ store.
• Jar with a tight-fit top for water
• Cloth to wipe your brushes on – a tshirt rag or old athletic wristband is reusable
• Paper towel – there’s nothing like it for dabbing at watercolors – tuck it in your wristband or under your paint while you’re working so it’s less likely to blow away
• Easel or Clipboard or Table (or plan on working with a sketchbook in your lap, like I do)
• Small DIY travel palette. This has black & white gouache & will someday have 3 primary watercolors in it, but I need to buy more tube paint for that.
• Paints, of course! I used a watercolor paintbox for the test. I will bring watercolor markers when I’m not working right on my porch, as they take up less space & use less water. I got lazy here & grabbed the paint that was already out.

Things to Think About

If you get impatient, like me, bring enough paper so you can work on multiple paintings at once. That way you can switch between them, leaving ample time for each painting to dry before you continue. I generally have 4 rectangles of paper taped into my sketchbook, so I can keep it open & just rotate to a new painting.

If you are pressed for time, consider painting at home & save the excursion for another day. Remember, if you try to pack up wet paintings they will be ruined by the time you get home! I walked home carrying an open sketchbook once because I ran out of time. It wasn’t the end of the world, but it was quite annoying.

Another option to consider is using a “wet panel carrier”. It is a small briefcase-like box that (can you guess?) carries wet paintings. You can probably buy one, but you could also DIY one. You could even kick back, relax for a couple weeks until I make one, & then read my future blog post about it! (I’ll add a link here when I write it)

Kit For Humaning

• Seating of some kind (even if you work standing up, you’ll probably want to sit at some point!)
• Water
• If you like to listen to something while you work, wear your most stable headphones! This is not the time for ill-fitting earbuds you are constantly adjusting.
• Snacks
• Sunscreen
• Bug spray
• Lightweight jacket
• Umbrella or wide-brimmed hat
• Backpack (or a reusable shopping bag, whatever you’ve got) to carry it all
• Camera – the one on your phone will do just fine!

Obviously this is not an exhaustive list. It's going to change not only person-to-person, but day-to-day. Water is the most important thing here. Your paints will dry faster outside & so will you! Make sure you bring plenty of water to drink, even if it isn’t hot.

One More Thing To Think About

Be prepared to carry everything you need in & back out again. This is a literal ‘take only pictures, leave only footprints’ scenario. Many articles that I have read advise using ‘found water’ & ‘found objects’, but only do this if the location you picked specifically allows it! Also be aware of what might be in that ‘found water’. How might various pollutants affect your paints & brushes? This is always a concern, but especially after massive flooding or near construction sites.

What’s Next?

OK, we’ve got our painting kit together with our water & sun protection. Now what? How do we actually paint outside? We’ll cover that in a future article. When? I don’t know. Southern California is getting hit by a tropical storm, we’re about to go into another heat wave, & we literally had an earthquake as I edited this paragraph. This #EnPleinAir series will continue in a few weeks.

Next Tuesday’s Karin Wanderer Learns will be my 30th article! It’s going to be about Pizza & the Teenage Mutant Ninja Turtles. (My 20th article had my favorite vegan cake recipe.) I never intended to make KWL into a baking blog every 10 weeks, but I’m happy it’s turning out this way. See you then!

How Does Humid Weather Affect Paint?

It’s probably not very surprising that “water” is an essential part of “watercolors”, especially if you’ve read my last 3 articles! In this case the high amount of water in the air is affecting everything, so the problems & the solutions are all slightly different than what we’ve seen before.

The best humidity to work in for most paints, not just watercolors, is in the 40-60% range. Painting in high humidity – at or above 70% – is going to affect every aspect of your watercolor experience. This is true even before you start mixing paints.

Before You Paint

Museums tend to keep the humidity between 50-60% in order to protect the paintings hanging there. This is too dry for mold or mildew to grow, without being so dry that the paper or paint are damaged. If you can work inside near a dehumidifier, make sure it is running well before you start painting.

If you have been storing paint supplies in areas over 70% humidity, or near cold surfaces where condensation builds up (e.g. windows, water pipes, etc.), check all your supplies for mold & mildew before you start painting. Once watercolor supplies have gone moldy, they cannot be used. They will spread the mold to every pan, brush, & painting they touch. Any mold can mess with pigments. Some molds are dangerous to your health. There is no way to dry out your supplies enough to kill every single spore, so each time you add water to start painting you will just be re-invigorating the mold. I’m so sorry. If you see/smell mold, it’s over.

If your paper is not moldy, but has been stored in a humid area, test the paper’s sizing before you start. “Sizing” in this case means the treatment the paper has received so that it absorbs the paint properly without dulling the colors.

Properly-sized fire

Have you ever tried painting on printer paper & the colors end up washed-out or uneven? The paper wasn’t sized, & too much pigment ended up inside the paper instead of on top of it.

Poorly-sized fire

Sizing can be made of gelatin, starch, or a number of other ingredients that all degrade over time, especially in humid environments. Paper that has lost its sizing can still be used for drier media, or you can resize the paper using a product called Watercolor Ground. I have no personal experience with this product, but I want to try it. Watercolor Ground will let you watercolor on not only paper, but also metal, glass, plastic, fabric… just about anything!

While You Paint

There are myriad tips & tricks to weather the humidity a little better while painting. Please be aware, painting in extreme humidity can be dangerous. Sweat does not cool you as efficiently in humid heat & humid cold can sap your body heat very quickly. The following tips are more appropriate for painting in a poorly-insulated studio or out on your porch than on a mountaintop. Please read guides on proper clothing & safety equipment before painting en plein air (fancy art term for outside) in humid weather.

1. Do not paint in the most humid parts of the day, if you can avoid it. Mid-morning to early evening will be more comfortable for you & your watercolors, as it is comparatively drier. Want to know the best time to start in your area? Touch grass. Once the dew has dried, you’re usually OK to start painting.

2. Work on multiple pieces at once, if you can. Everything dries more slowly when it’s humid. If you switch between pieces, it’s easier to wait until each layer of each painting is really truly dry. Don’t muddy your colors or blur a piece just because you’re impatient!

3. Give your paintings lots of support. If you’ve painted even a single watercolor painting I probably don’t need to tell you how water can make paper buckle & ripple. That can be much worse in humid weather, & the paint is more likely to peel. Make sure you tape, tack, stretch, or otherwise secure your paper to avoid this trouble! The adhesive in tape can fail if it gets too wet, consider using binder clips.

4. I don’t think I can emphasize enough how long everything is going to take to dry. It will take forever. Maybe even twice that. If your paper looks dry but feels cool to the touch, it is still damp. Give it more drying time!

5. Turn on a fan. You may not want it pointed directly at your paper, but keeping the air moving will make everything better for you & your painting.

6. Switch to a different medium entirely! I recently switched from ​300 lb (640 gsm) watercolor paper to cardboard from a cereal box, as well as using ink along with my paint, as the humidity fell so low the “water” part of my colors was evaporating before I could work.

‘Art differently’ may not be my favorite tactic, but it is a tactic. Thinner paper, less water, or switching entirely to pencil, charcoal, or markers, will all work better at higher humidity than watercolors will.

Happily, there are other solutions. For example, there are a number of DIY solutions you can add to your water to make the paint dry faster. Read I Started This Heatwave & revel in my meticulous #WatercolorScience. Those experiments were focused on keeping the paper wetter for longer, so several solutions which were considered failures in that experiment could be immensely successful in this one!

After You Paint

Be patient! This goes for your painting as well as you paint pans & palette. Everything needs a long time to dry, preferably undisturbed. Give it all as much time as you can! Some paint companies recommend sticking your paint pans in the freezer if it is too humid for them to dry properly- check with your specific paint manufacturer. Do not freeze paint tubes! Read When Winter Comes Howling In to find out why. Many people will let their paint pans dry as completely as possible before storing them & the paper with those little silica gel desiccant packs to be extra safe from moisture build-up.

We Didn’t Listen!

Something went wrong, & now your paintings are moldy. Don’t cry- that will just make it more humid. You may be able to fix this! Here is a link to the Museum of Modern Art’s guide to fixing molded paintings

Turn A Bug Into A Feature

There are countless wet on wet watercolor techniques, & you will have time to play with all of them on a humid day! There are also many desiccants, such as salt or sand, that will soak up moisture. The world is your oyster- dehydrate that sucker!

I Want YOU To Do #WatercolorScience

I live in an area experiencing a drought, so I can’t test any of these solutions. This is your chance!

I’ve spent the last few weeks writing a series of articles on how to paint in extreme heat & low humidity. These two conditions lead to your paint & paper drying fast. They have been making my life very difficult recently! However, I don’t want to neglect my peers from other hemispheres, my beans from other scenes, my legions from other regions… Don’t want to season shame anyone.

So if you want to learn how temperatures over 90°F (32°c) can affect your watercolor painting, various techniques that can help you watercolor in hot & dry weather, as well as a number of solutions you can buy to help you in this endeavor, read Part 1. If you would like to read all about my #WatercolorScience experiments with DIY solutions for hot & dry weather, read Part 2. If “hot & dry” are not your current problems, read on!

How Does Cold Weather Affect Paint?

Watercolors, as the name implies, rely heavily on water. If you have to paint at or below 32°F (0°c) your paints can literally freeze. Tube paints are more susceptible than pan paints, as they have a much higher water percentage. Previously-frozen paints can end up with a grainy texture & are more likely to develop mold. Paint tubes subjected to freezing temperatures are more likely to rupture as the paint expands & contracts.

Paints Are Like Human Beings

There are myriad tips & tricks to weather the cold a little better while painting. Please be aware, painting in extreme cold is much more dangerous than painting in extreme heat. Sitting still for the long periods of time required to paint helps you stay cool on hot days, but that is exactly what you want to avoid in the cold- even above freezing temperatures! The following tips are more appropriate for painting in an unheated studio or out on your porch than on a mountaintop. Please read guides on proper clothing & safety equipment before painting en plein air (fancy art term for outside) in cold weather.

1. Do not paint in the cold, if you can avoid it. Working in the middle of the day or early evening when it is comparatively warmer will be more comfortable for you & your watercolors.

2. Work smaller, if you can. Cold paper dries more slowly. If you can finish fast enough, neither you nor your paints will have time to freeze up.

3. Give your paintings lots of support. The water can freeze as it dries on the page, which can crack if your paper is bowed or bent. The adhesive in tape can fail at low temperatures, so consider using binder clips or a watercolor pad instead.

4. Recognize the effect freezing will have on your painting, even if it doesn't crack. When you bring it inside it will thaw & need to re-dry, which can make your picture muddy & blurry. This is probably not the time for an extremely detailed masterpiece.

5. Switch to a different medium entirely! I recently had to switch from watercolors to ink mid-painting as the temperatures climbed so high the “water” part of my colors was evaporating before I could work.

‘Art differently’ may not be my favorite tactic, but it is a tactic. Pencil, charcoal, alcohol-based markers, & oil paints will all work better at lower temperatures than watercolors will.

Happily, there are other solutions. For example:

The Cause Of – And Solution To – All Of Life’s Problems

Alcohol is the famous answer here. Traditionally, painters have added anything from gin to vodka to their water to keep it from freezing. This absolutely works for watercolor paint! Painters have also traditionally added it to themselves “to keep from freezing”, but this is a myth. Drinking alcohol makes you feel warmer, but makes you cold faster. So far as paint is concerned, mix the alcohol in with the water used to dampen your paint pans, brushes, & paper, as well as the water you wash brushes in. ⅓ to ½ alcohol seems to be what most people prefer. This will damage brushes, don’t use your nice new ones for your boozy painting.

PSA: Do Not Use Rubbing Alcohol!

I tried this once, to see if it worked like DIY alcohol inks. It does not! The watercolors gets all gross- on the palette, the page, & in the pan. I ended up washing a fair amount of paint down the drain trying to make sure it was all rinsed out of my paint pans!

DIY Solutions

Putting your palette on an electric heating pad or radiator set to “low” is almost certainly a fire risk, but it is a suggestion I have seen several times. Your metal & ceramic palettes could easily get too hot & your plastic palettes could melt! I wouldn’t even mention it, except it keeps being suggested online & I wanted to emphasize how easily that can backfire.

Warm water. Seriously, try it. Hot water will damage your brushes, but warm water will take longer to ice up.

Turn A Bug Into A Feature

Work with the freezing temperatures to make new, cool art! Many different artists have experimented with intentionally letting their paintings freeze. I tried to do this in my small freezer, it resulted in a muddy mess! People who work outside have gotten very nice results, though.

I Want YOU To Do #WatercolorScience

I hate the cold. I am very dedicated to never being cold again, & I live in an area that doesn’t get very cold even in winter. In other words, I can’t test any of these solutions. This is your chance to shine!

Test the various solutions in this article & any tricks you may have of your own, then send me your results & pictures! That way I can write a #WatercolorScience article for cold weather. You can contact me on Ko-Fi or Mastodon. Please include the name/user name you would like me to use so I can give you proper credit! I can’t wait to hear from you!

In Part 1 of this earthshaking, dream making, groundbreaking blog duology I explained how temperatures over 90°F (32°c) can affect your watercolor painting. I explored various techniques that can help you watercolor in extreme heat, as well as a number of solutions you can buy to help you in this endeavor. Sadly, all the proposed solutions were outside my budget so I could only discuss options instead of testing them. Happily, this week we are talking about DIY options using common household items! Roll up your sleeves & strap on your safety goggles, Part 2 is all about #WatercolorScience!

You Can DIY A Solution

The internet contains a literally infinite amount of DIY art solutions. Some are sensible, some are ridiculous, & some, like a cat flap, are so ridiculously obvious it takes a real genius to point them out. With a small amount of time for testing I chose to limit my experimentation to 5 DIY solutions in 2 groups.

The Solution is in the Water

These solutions were added to the water I used to coat the paper before painting. I tested adding dish soap, ice, vinegar, & witch hazel. Some are meant to make the paint spread out faster, some are meant to make the paper dry more slowly, & some are meant to do both. The solutions make the paint spread faster by destroying the surface tension of the water. If you follow me on Mastodon, you’ve already seen my post explaining surface tension. If not, here we go!

Liquids like water (or, in the example below, oat milk) have a high surface tension; the molecules hold tightly together. That’s why water can ‘mound up’ over the top of a cup before spilling, & why some insects can walk right across the water’s surface. When you add a solution that lowers surface tension, like dish soap, the water molecules stop holding tightly to each other & instead spread themselves out as much as possible, as seen below!

This is the first video I ever made for this blog. It is truly an historic moment in both scientific & cinematic achievement!

Experiment Time!

I brushed on the solution, then painted a green flower shape using the wet-on-wet technique to see how the paint flow & drying rates were affected over time. Vinegar & witch hazel behaved so similarly I only photographed vinegar’s results. Here are my super science results:

The ‘A’ card is my control- just plain water. On a day over 90°F (32°c), with no fan, it was bone-dry in 7 minutes.

Dish Soap The ‘B’ card was soapy water. As you can see, the paint disperses faster, just like the food coloring in the video above. However, it also dries a lot faster. It hardly blurs from the 3 minute mark on, whereas plain water was blurry past the 5 minute mark. Considering how many claims I saw online about soap slowing drying time, I was surprised!

Ice Cubes The ‘C’ card is for icy water. Cold water evaporates more slowly. It seems so obvious when I say it out loud! I felt genuinely foolish that this had to be pointed out to me- but it works.

Vinegar or Witch Hazel The ‘D’ card is for vinegar, which behaved exactly like witch hazel in that neither worked as intended. The paint dried noticeably faster, even though at this point the temperature had fallen & the humidity had risen slightly! I declare these both to be complete failures.

Winner: Ice water. Who knew?!

The Solution is in the Paint

This was suggested for watercolor paint that comes in a tube instead of pans, so I could only test it with gouache. I mixed the smallest drop of honey I could squeeze out of the bottle with about 4–5 times the amount of paint using an old supermarket rewards card as a palette knife. It mixed up much more easily than expected! That was the last part that went more easily than expected…

Mixing honey with pigments to make paint is old- we have literally found this mixture in cave paintings from Neolithic times. It was also used in Ancient Egyptian paintings & illuminated manuscripts. People still use it to make their paints today! It makes your colors brighter & shinier. If you use a light-color honey it barely affects your colors! I have seen honey that is practically clear that would be perfect for this. I was using black paint for this experiment, so I didn’t worry about the color of honey.

This worked much too well. As you can see from my test papers, there is an enormous difference in drying time between the lines.

Line ‘B’ was plain gouache. Whether used fresh out of the tube or left to dry on a palette & rehydrated, it dries on the page inside of 3 minutes. Honeyed gouache just… doesn’t dry at all. 30 hours after the initial experiment, the gouache on the test paper was still tacky – like it usually feels about 2 minutes after painting. The gouache on my palette was still wet! It was shiny & sticky, like fresh tar on a hot street. I have watched videos of people making paint with honey so I know that works, but adding it to already-mixed paint was not the easy solution I was promised by internet randos.

[Friendly Neighborhood Karin here. 60 hours after mixing honey & paint, all the honeyed paint was still wet. 90 hours after mixing, it was still a bit sticky but dry enough that a sealant spray might have worked. I have no sealant spray & so just threw all the honeyed paintings away.]

Winner: Nobody. Well, maybe the ants who find these honeyed paintings in the trash.

Xtreme Climate Conclusions

I’m so pleased that ice water is the clear winner here. What an easy, inexpensive solution. I’ve started dropping one ice cube into each of my 2 water glasses when I start painting on a hot day. Adding a lot of ice (as I did for the ‘C’ card) means that sometimes a bit of ice can stick to your brush & you end up carrying it to the paper, which messes with your water levels. One cube is plenty. Put the rest of your ice into your drinking water- you need to stay hydrated too!

This multi-part extreme weather blog has been a blast! Thank you to everyone who sent me suggestions. I am spending this week doing a series of free watercolor workshops (made possible in this weather by ice water!) See you next week!

This is an ongoing series of #WatercolorScience articles about how different types of weather affect your painting, even if you work inside.

Human Beings Are Like Paints

Both react poorly to heat. Dehydration becomes a larger & larger concern as the temperature climbs. Where I live, the temperature rising is generally combined with the humidity falling, which leads to even faster dehydration. As extreme heat waves become more & more common, we are going to have to adapt how we do a lot of things, from growing our food to building our homes. Those are issues I will leave to architects & agricultural experts, however. I will be talking about a different subject: how to watercolor in extreme heat. There’s a lot to talk about because, as you will see-

Paints Are Like Human Beings

There are myriad tips & tricks to weather the heat a little better while painting.

1. Do not paint in high heat, if you can avoid it. Working early in the day or late at night when it is comparatively less hot & more humid will be more comfortable for you & your watercolors.

2. Be aware of how much heat your light source is contributing. Painting in direct sunlight (even if you are inside) or under a hot lamp will dry everything out quickly! When it gets over 90°F (32°c) I use my somewhat dim ceiling light to paint as much as possible. I turn my bright/hot lamp on only for mixing color & painting details. The difference it makes is remarkable!

3. Work smaller, if you can. When it gets over 100°F (38°c), if I absolutely must paint, I won’t paint anything larger than 2 x 3 inches. If the paper is small enough, you can paint fast enough to beat the accelerated drying time!

4. Add water to the back of the paper, then tape it to your work surface. The paper will stay damp longer if both sides are wet! I have seen this as a tip to avoid the paper rippling, but it also helps keep everything hydrated on hot days.

5. Add water to everything! Mix your paints a little thinner than usual, wet your paper a little more than usual… You know the poem; “water water everywhere, so let’s all have a drink.” Get yourself a spray bottle with a very fine mist, & you can mist your paper, your paints, even yourself!

6. Switch to a different medium entirely! I recently had to switch from watercolors to ink mid-painting as the temperatures climbed so high the “water” part of my colors was evaporating before I could work.

While ‘art differently’ is certainly a tactic, it may not be the best tactic.

Happily, there are many other solutions. In fact-

You Can Buy A Solution

Several, even. There are a variety of products you can add to either your water or your paint to extend drying time. These products can also make the watercolors more glossy, more transparent, more textured, or more pearlescent, so test before using! I have not tried any of these products & therefore cannot make any recommendations.

Gum Arabic is the hardened sap of Acacia trees. It is a common ingredient in many watercolors already. It will make your paint dry more slowly, giving you more time to work, while also making the paint appear more glossy & transparent. You can mix it into the water or the paint.

Ox Gall Liquid is not vegan. It is a fluid harvested from bovine (usually cattle) gall bladders & mixed with alcohol. Some watercolors use ox gall as an additive ingredient. If having a vegan art kit is something you value, check the ingredients for each individual color- especially shades of black.

Synthetic Ox Gall Liquid is vegan. Both versions of ox gall reduce surface tension, increasing how much & how quickly the paint flows. They both extend drying time. You can mix both into the water or the paint. You only need a few drops! Too much can dull your colors.

Watercolor Medium is a confusing name. All the products in this section are referred to as watercolor mediums. Watercolor Medium, however, is a specific product. It increases the paints’ gloss & saturation, like gum arabic, as well as the speed & extent of the paints’ flow, like ox gall.

Tune In Next Week For The Epic Scientific Conclusion!

I thought this could be done in one week but it is getting long. I’ve been experimenting with adding various solutions to my water & paint to beat the heat. Next week I’ll share the #WatercolorScience I’ve been engaged in!

This isn’t a mess, it’s science!

Making this a 2-part series means you had an opportunity to share your watercolor wisdom! Thank you to everyone who sent your tips & tricks to me via Ko-Fi & Mastodon! I absolutely loved trying as many as I could that week!

This is an ongoing series of #WatercolorScience articles about how different types of weather affect your painting, even if you work inside.
