Hi,
I was poking at a variant of HSV I did not know about to satisfy my curiosity, having thin hopes that it could do something better than HSV: HCL by Sarifuddin and Missaoui (2005).
Unfortunately no cigar, it is even worse than HSV!
sRGB Colour Wheel
ACES 2065-1 to sRGB Colour Wheel
Tasty Negative Colours
HSV Saturation Compression
No More Negative Colours
HCL Chroma Compression
Unsurprising Disappointment
I was considering porting it to Nuke initially but given those results it will stay as Python in my world. You can find an implementation in this issue.
Cheers,
Thomas
