These last two layers started with a coat of blue paint, but not just any blue. I have a favorite mix of green and magenta that produces my favorite blue. I know, you’re saying that combination can’t possibly make blue. I didn’t think so either until, long long ago, I tried it. The catch is, it works great with phthalo green and quinacridone magenta–probably because they are both transparent synthetic pigments.
On top of that layer I used the same mix, but threw in a generous dollop of dioxazine purple–another transparent synthetic pigment–to create a lush purple. This background is now millimeters away from ready. One more layer of the purple in a few spots should do it. Then the drawing below will be laid on top like a coloring book outline in reverse. If you saw my posts for Sky Pads 27 you’ll recognize the technique. I have to put white lines on the canvas when I project the drawing because it’s so dark I wouldn’t see anything else.
