The idea I shared was to work on a sheet of watercolor paper with an underpainting. I prepared 2 sheets the night before, both using a triad of primary colors. The following 2 paintings were painted over an underpainting of alizarin crimson, aureolin yellow, and cobalt blue. The floral was painted in Tuesday's session.
I haven't figure out how to finish this piece, but it's been fun dropping in a mixture of colors and painting around the shapes.
