The best color selector？

[TheTwo]

I was just reading Björn Ottosson’s article. In it there is a summary of the various models and two new models are proposed：

	HSV	HSL	HSLuv	Lab-like*	NCS	Okhsv	Okhsl
Orthogonal Lightness	no	no	yes	yes	no	no	yes
Orthogonal Chroma	no	no	no	yes	partial	no	no
Orthogonal Saturation	partial	no	no	no**	no	partial	no
Orthogonal Hue	partial	partial	partial	yes	yes	yes	yes
Simple Geometrical Shape	yes	yes	yes	no	no***	yes	yes
Max Chroma at Edge	yes	no	no	yes	no	yes	no
Varies Smoothly	yes	yes	no	yes	yes	yes	yes
Varies Evenly	no	no	no	yes	partial	no	no

We can see that “Lab-like” has the most “yes”. One of its shortcomings is “Orthogonal Saturation” which is not well done by other models. The other is Simple Geometrical Shape:

LCH has a dynamic color picker. But it tends to be triangular, which is an advantage: it is always “low saturation” in areas close to white and black. However, the current three-level color selector is only the HSL model.

GIMP also has an LCH color picker. It may be made by cielab, so the hue is a bit strange. The LCH produced by Oklab is more ideal. It is said that photoshop2022’s new update on gradients uses oklab
