I wrote a new sample for MacRuby Graphics that samples the colors from a jpg and display them. I was trying to find a good way to sort the colors in a way that makes total sense (sort by color family and by brightness). Unfortunately, this isn't an easy thing to do, here is the result:

I'd be curious to know if one of you knows a better way to do that?

IIRC, you usually convert from rgp to hsv and sort on [h, s, v] or [h, v, s]. I can't tell from your code sample what the sort is doing.
