Anyway, it's all done with colored scribbles in Painter--at 72 dpi, it smooths out a lot, but up close, it's incredibly scribbly. I kinda like the effect, ultimately.
I'm feeling pretty good about these color experiments. I feel like I realized something important about color, or applied it in a new way, or something, although I couldn't say exactly what. Maybe it was just "Quit worrying and scribble, stupid." Which is maybe important in a totally different way.
