I think the reason we are seeing little of the chromatic set is that it is basically different shades of yellow, orange, purple, blue and green.
The muted colors you are seeing is because of the blending. With blending the luminousity is destroyed.....the colors become muted. The color of the paper is gray.
In order for me to cover up the color of the paper I am forced to blend. I haven't yet been able to force myself to let the paper show. If I were to let the paper show, and not have so many compressed layers the colors would burst....and I think the paintings would look a bit more jagged... loose
Thanks for the pointers, Blayne. It gives me some things to think about and correct. I hope to soon produce work that I can try to sell. A local (well, 30 minutes away) flower shop saw some of my paintings on my phone and told me they would love to hang some of my work and sell it. They might just be blowing smoke.
