Reminds me of a blog post on using PCA for sorting colors

This is an interesting presentation of a non-trivial problem. Does anyone know of any good resources for learning more about color spaces?

The best resource on the web is http://handprint.com/LS/CVS/color.html

To be honest though, books are better than anything on the web. Here are a few good ones:

As for the link under discussion.... meh. RGB (and derivative color models like HSL/HSV) are terrible for color sorting, because they have very little relation to the way humans see color. Trying to sort a three-dimensional quantity into a single linear order in some “best” (or even “reasonable”) way is inherently futile. I guess it can be fun to play with, but IMO isn’t very “practical”.
