For the weekly. I think it uses all the colors.
This is my band teacher. His name is Mr. Webb. Despite being pixeled from a real thing, no reference was used.
Looks like a character from a sci-fi universe.
I took a couple liberties in the proportions on his face, so I suppose he looks a bit more curmudgeonly than usual, but I see what you mean. ;)
I think I'd be a bit scared if he were my teacher, he looks like (how can I put this tactfully) a bit of a loner! :)
