For those asking for a light theme/theme similar to Moi3D, took a shot at it.
There's some crossover in what's selectable/adjustable (i.e. where the contrast colors reverse) so somewhat limited in balancing it out, but it's something for now.
Recommend using "color_matcap" for the most similar affect (see screenshot, RIGHT+CLICK render ball icon). And I also included some commenting on what I could figure out, and a very visible purple color for visualization on what wasn't adjusted in case you'd like to change more.
