Is it bad that my first question on seeing that page is "What color space is he doing the nearest color calculation in?"? HSB would do a lot better than RGB, no?

Since you choose colors in HSB, I'd assume that the math is done in that space as well.

Empirically, the colors seem to make up tiny cubes in HSB space. If they were in RGB I don't think you'd see that kind of coherence.
