Yeah, one whole day of it, including half an hour of standing in front of a pot of boiling water.
I never enjoyed coloring as a kid, plus it took about an hour for each of these. And then I remembered that originally I was going to print the contours on drawing or water color papers, but I forgot and printed them on regular cartridge paper, so there was a limit to what I could do.
I used water color pencils because I have a hard time mixing paint to get colors I'm after, but then I remembered I also have a hard time wetting water color pencil marks. In the past I've tried brushes, paper towel, sea sponge, and fingers, but regardless the pigments seem to collect in one area leaving the rest pale and watery. Today, I tried steaming from the wrong side, then the right, but after 25 minutes at the stove, I saw an ever so slight hint of change on the surface. Then I stumbled upon my broken plant mister, so that's what I used, over and over and over again. That was a good stress relief.
I'm not sure if I learned anything from the day's experiments. Other than water color pencils still being a difficult medium to use if I want saturated color areas. And that Grand Canyon upside down looks a little like a mountainous island.
