I've always been marveled at GIMP and very happy that it's so accessible.

I was wondering if I can ask, I'd like to know how indexing works and creation of a palette, it happens so quickly that I was wondering if anyone could tell me (even if roughly) how this indexing works. Or even point me to a an article or the name of the creator of this particular algorithm.

I attach an image of what I am talking about.
