color model conversion in emacs lisp

For emacs lisp coders, there's a newish color package 〔color.el〕, bundled with emacs 24.3 at least.

the package lets you convert colors from various models and formats. ⁖ RGB, HSL, HSV, named color values, and things like finding the color complement.

call describe-function on color-rgb-to-hex and you'll have a link to it.

it's written by Julien Danjou, Drew Adams. Superb. Thanks guys.
