You could make it hundreds of times faster if you calculate with
images, not pixels. But maybe it's fast enough already? It depends on
your needs.

CIELAB would be a better colour space than RGB, but I don't think PIL
supports CIELAB colour space, so you'd need to look into another image
processing system,  like numpy or vips.
