Cadmium Yellow, Quinacridone Red, Phthalo Blue (green shade), Titanium White, Mars Black. That's the limited acrylic palette I've been using since Bill Park's workshop at the beginning of January. I am amazed and intrigued by all of the color mixing possibilities of these few colors. Speaking of limitation, I have been working with a single subject for all of these paintings, too. A printing apron (courtesy of Bill Park, thank you!). One subject, endless ideas. John Entwistle, "Apron Strings."
