The input I've gotten so far removed any remaining doubt about porting
those layer modes to LCH, so I've done that now:

Bug 401754 – Port Hue, Saturation, Value to CIE LCH

Nice work Martin :-)
I'm trying to make a valid comparison of the two images from PS and
Gimp but it seems like the have block distortions from jpeg
compression or something?
I mostly use the color layer mode for overlay painting on black and
white sketches. Here is an example of the use:

Problems with real-time responsiveness when using LCH is a good point,

I very rarely use layer modes (and I'm not a GIMP hacker so I'm probably
missing something), but if using internally CIE LCH fo
Hi,
The "Color" layer mode has since long produced bad results, see bug
325564 [1] for a way to see this. The cause is a combination of rounding
errors due to 8bit processing and poor properties/usage of the
underlying color model HSL.
I have just implemented Color based on the CIE LCH color m
