There's a lot of blue and purple. Not a lot of bright white, and I didn't see any face icons that were outright dark, borderline black. I figured Jinx fit more in with the violet shades considering the high contrast there, but she could be moved to the white category.

What do you guys think of this champion icon breakdown? It's not all of them. I'm not patient enough to go through and make sure I've used all the icons. This is only 90 faces. Some of the others are hard to place because they're hybrids. Shaco for example is half red, half violet.
