I don't think I've been doing enough in the past few weeks to promote the use of gouache, so here's a piece I did as an in-class demo in February. It's a quick sketch made from a pepper I didn't eat at lunch, followed by a quick throw down of color in and around the pepper to make some teaching points. The red side of the pepper I developed a little bit more to show some reflectivity and shading. The stem shows some blending of colors but isn't at the final level yet. The yellow is an attempt to show how I'll work up some different colors over dark colors below (but we ran out of time). The blue background shows how you can work in white and change things up. All this happened in less than 25 mintues, while I was talking, and working in various places while paint dried to the appropriate state in others, and so it goes, you keep moving. I think you can see the possibilities, whether with dry brush, or to blend.
And gouache always looks so lovely on toned paper.
You might want to try some.
Oh, I used a small filbert for all the strokes here because there wasn't time to change brushes .
