I made this change in some places, but didn't do it for things like loops through channels. As is, I went from 580 cases to 1800+, but there may be other places where specificity is worth it. |

There was a problem hiding this comment.
@nex3 Using ColorJS to do color conversions works, but the math isn't precise enough to pass these tests, e.g.:
expected color(xyz-d50 0.66406985168935 0.5367266828656 0.43459579340121) to be .equal() to color(xyz-d50 0.6640698533004 0.53672666252811 0.43459582467203)
I'm not sure if we want to relax the precision requirements, or have different precision requirements for different platforms, or...?
