Gouache is opaque watercolor paint. Somehow I aquired 41 tubes of it. "Who bought it? Oh, I did." I took all the qouache out of the closet and organized it on my desk. Then I made a color sample chart to see how each brand and color looked. I made some interesting discoveries. The Giotto brand of gouache I bought in France two years ago was dry and didn't have much pigment. The cheap Reeves brand gouache I bought at Michaels 5 years ago was fine. Both the Winsor Newton brand and the Holbein brand were excellent.
I am declaring this week, Gouache Week. To observe Gouache Week I plan to paint a picture in my sketchbook every day with gouache. Want to join me?
