Possible summer project

This is a doodle from my sketchbook.  I was thinking I could do maybe 22 x 30, paint them with acrylic paint, perhaps choose a color scheme that will lend to optical mixing, like Seurat.  I might leave black outlines visible or maybe no outlines at all.  As for the background, I might start off by leaving the white background of the paper.  If I do a series, of course I would try different things: colored background, different color schemes, perhaps imbed an image within the circles.
