My garden is filled with clean, intense beautiful flowers including torch tithonia and zinnias. Usually daily, I paint some of them. Most days, I also wipe these little paintings. As soon as I add white to the colors, they lose their intensity. Consequently, the painting is not at all what I want.
Today, I started again. I painted with transparent colors as long as possible and then tried to keep from "snuffing out the life" of the painting with the opaques (including white).
