If you are a beginner with watercolor painting, or even if you're not ( ! ), you may want to lay out your palette with a sheet of watercolor paper under it, paint a blob of each color on the paper, and then write the color name next to each (the images below help illustrate what I mean).
It’s important to be consistent with the colors you use in order to give your painting a cohesive look. If you mix a color you like it’s important to realize how you did it so you can do it again! Knowing your colors is so very important!
Keep a color wheel handy. I’v painted over 1,000 (at least!) original watercolors and I refer to it often!!! Please let me know if you have any questions and I would be happy to help.
