Worked: (newest version of Blender that worked as expected)
Short description of error
The color jumps erratically by adjusting the lightness value, worse the closer to black
Seems to converge towards specific colors (see video).
Doesn't seem like node colors are affected.
Exact steps for others to reproduce the error

Changed status from 'Needs Triage' to: 'Confirmed'
Can confirm.
First I thought this was a duplicate of #69562 (Manipulating saturation of colors (e.g via HSV or RGB curves, but also within color picker) shifts HUE) -- and it might be related as well --, but seems to be another issue in play as well.
This affects theme PROP_COLOR_GAMMA colors a lot more then other PROP_COLOR_GAMMA colors for some reason. And this also affect RGB sliders.
It is definitely a duplicate of #75876 (Changing value affects hue & saturation in 3D view gradient color sliders), but not sure anymore if #75876 is really a 1:1 duplicate of #69562
UI: Erratic color picker on lightness changes.to UI: Color picker lightness/value changes Hue and Saturation (only in Preferences > Themes?)Ah wow, that does look related. I only searched for color picker tasks and found none.

FloatVectorProperty
props don't show this behavior. It's like there's something specific to the theme color props. Not sure how they differ from colors by python api.Added subscribers: @blanchsb, @ankitm
