Comment:
><rgrout> when comparing colors, do we compare the floating point tuple or
should we scale by 255 and round and then compare?
><rgrout> so I guess I'm asking how picky do we want a comparison to be?
Should it be more of a perceptive comparison or more of a numerically
exact comparison?
><kini> perceptual similarity is not transitive
><kini> though rounding to the closest 1/256 is not exactly a perceptual
comparison
I agree with slabbe. The patch gives me doctest errors. Please fix them!
(Specifically 'green' is not (0,1,0).)
