One of my little passions is color theory. Lately I've been
experimenting with the Luv and Lhc color spaces, which are supposed
to have more perceptual uniformity than RGB, CIEXYZ, or the
especially hideous HSV color spaces. This is a little gadget I wrote to
explore Lhc color space; it requires a DOM v2 browser (basically
either IE 5 or later, Netscape 6 or later, or Mozilla 0.97 or
later). I'm also working on a theme
generator and on a palette discovery system, but those aren't
really ready for public consumption.
