Lab Color Sliders or Tone/Luminosity Lock
Posted: Sat Sep 12, 2020 1:15 pm
Hello, I'd like to contribute with another suggestion about this kind of sliders. I saw other threads on a similar subject but nothing was implemented so far. This is one of the few things that I feel is missing from Paintstorm.
I work at a game studio and for a year now, me and my colleagues have bee using Lab sliders instead of HSB.
Sliders would be enough, no need for a new color wheel.
Here is a link with a rudimentary example for the reason why:

Basically Lab allows to modify the Hues whitout affecting the perceived values.
Here is a link to a tutorial made by Mike Azevedo with a more ample explanation:

Wikipedia - "Unlike the RGB and CMYK color models, Lab color is designed to approximate human vision. It aspires to perceptual uniformity, and its L component closely matches human perception of lightness."
Also, as an alternative there are "Tone Lock"/"Luminosity Lock" options present in Anastasy's Magic Picker/Coloorus plugins for Photoshop:

In the case of Magic Picker, I know that "Tone Lock" was implemated a long time ago at the request of Disney colorists.
I don't know which one is easier to implement but it would be really nice to have any of them. It would help complete the an ontherwise really good package.
