I began in traditional oil painting and set up my palette years and years ago. Now with acrylics it's the same layout but with this Masterson system....a covered vinyl box with a thin wet sponge and a special palette paper. It allows me to keep my acrylics fresh for weeks. The way I layout my colors never seems to change, I mix from these colors adding very little black. Starting from the upper right is Quinacridone Crimson, Naphthol red light, cadmium orange, cadmium yellow medium. On the left at the bottom: Phthalo green (blue shade), Phthalo blue, (green shade, Ultramarine blue, Dioxazine purple, mars black and white in the top center. I mix in the middle and it's great when I want to grey down my colors, orange into blue, yellow over to purple and red to green. Right now the center needs a scraping and although stained, I can mix more colors.
I've been in the studio today....exploring new and old techniques. Seeing what feels good, looking through my stacks of papers and such....writing in my journal, an easy day.
