I don't know if I have a minimum range yet. I do think certain lightness ranges can tolerate more hue shift. Like really dark colors can tolerate more, and maybe...

@LeaVerou Yeah, I realized what you asked, I just don't have an answer yet. I probably didn't make that clear. I had not yet considered deriving such a metric, though...

I take it back, Scale LH does improve considerably, but you must correct both L and H in both iterations. It still saturates high lightness more than other approaches, but...

In my opinion. 1. I think it should short-circuit out if a color is already in gamut. While some gamut mapping algorithms can do this, it sounds like, as a...
