A couple summers ago, I took a watercolor class where I learned that I could make a variety of colors by mixing only primary colors together: blue, yellow and red. All my long life, I’ve used pre-mixed colors in my paintings, and even though I mixed those premixed colors together to get other colors, it was a revelation that I could start with just the three primaries and get a variety of new colors.
I also watched a DVD titled Painting with Watercolors by Kateri Ewing, and in that video Kateri explains how to make simple color charts with watercolor paints.
I used a warm and cool of each primary for my color chart. Warm and cool describes the temperature of each color – you can learn more about that here. Also, each color is made up of pigments. A red color from one company may look slightly different than the same red from another company, depending on the pigments used to create that red. Pigments are listed as numbers on my watercolor tubes. I listed those across the top row.
I’ll add some dark colors, too, which I still need to test. A color chart will be handy for me when I’m looking for a particular color in my watercolor paintings. For example, I can refer to the chart and know which colors I need to mix up to get just the right purple. I’ll let you know how it goes in future paintings:)
