My favorite art to make lately has been painting color wheels with watercolor paint. This probably my favorite one so far. It is a color study of five pigments.
Sometimes I paint little color wheels to test out colors or an idea for future reference. I made this color wheel to test out a very red heavy color wheel. It uses both black and red ink.
I'm making myself a little book of color swatches, including a few color wheel, such as this one.
I used that one to help me paint this piece.
Some of my color wheels use a combination of traditional watercolor paint and mica paint, which looks metallic and flashes in the light. See the rainbow flash?
This color uses two reds, two yellows, and two blues, mixed in pairs.
This color wheel also uses two yellows, two reds, and two blue, plus I used colored pencil on top to add the shading.
