color histogram?

[Chipp Walters]

Hey guys, I'm building another education app for a state school system, and
this time I'm creating a skinnable themed desktop, which kids can add their
own wallpaper to. I'm wondering if anyone has a quick routine to calculate
the 'main' colors of an image-- so I could automatically theme the button
colors and some other objects.

If not, I'll have to write my own. Thx.
