Dominant color & PIL

[Rinzwind]

For example:

getdata

im.getdata() => sequence

Returns the contents of an image as a sequence object containing pixel
values. The sequence object is flattened, so that values for line one
follow directly after the values of line zero, and so on.

Note that the sequence object returned by this method is an internal
PIL data type, which only supports certain sequence operations. To
convert it to an ordinary sequence (e.g. for printing), use
list(im.getdata()).

So you could get them and count them in :)
Don't know if you should do that on a 1600x1200 wallpaper tho :D
