What I don't like in standard HSV color picker [1] is that the colors are distributed non-uniformly. For example, there is a wide area of same looking green color, but just a thin line of yellow and orange. I didn't understand if new models solve this issue.
Thank you for the link, very interesting. Now I see there's another problem: the colors on the hue bar (especially with OKLrCH model) look too blurred and mixed with each other. And there's almost no green, but mostly reddish and blueish tones.
