This adds a "random color sampling" section to the right side of the debug page.
I'm hoping this will make it easier for @mittimithai to work on his random color code, since it shows a bunch of random colors (100 right now) side-by-side, rather than requiring the developer to constantly click "randomize colors" on mandala/creature to get an idea of what the color spectrum looks like, 3 colors at a time.
