When changing color, changing one channel of HSV makes changes to all other fields, instead of the one.

Adjust color of cube, for example. Change it to saturated red, go to HSV, change hue and saturation will decrease as well.

Can confirm that. Looks like a conversion inaccuracy. It's interesting that this problem did not appear in Blender 2.79. What is different now, @Brecht Van Lommel (brecht)?

Filmic view transform by default perhaps?

@Brecht Van Lommel (brecht) can I merge this with T58014 ? I'm quite sure that this is the same problem.

It's not the same problem.

I checked an older build 4c31bed6b46 from roughly the 30th of November. Both the issue I've reported (T59306) and this one aren't there. The issues are probably related.

I remember having this issue back in the alpha, however it was fixed. I would link you to the commit, but I can't remember the name or many other details making it hard to find.

It reminds me to some months back when matcaps, the HSV color picker, and the lookdev hdrs were all filmic. Now it's better for the matcaps and lookdev, but the color picker is hard wired to corrected filmic, regardless of the color management settings. There should be more options for the color picker, depending if you want the HSL and HEX to be corrected for srgb, filmic, your scene color management settings, etc
