A work in progress. I decided to push myself further than just doing the contrast between black and white. I’m using other sets of contrasting colors (red/green, blue/orange, etc.) to try to define the tone of the figure as well. So for the first layer, I only painted the areas I perceived as being more black than white. Layer two, I only painted the areas I perceived as more red than green. Then more purple than yellow, and then more blue than orange.
