LateNight knob notches blend with background for red-green colorblind users

Red looks like brown. See attached screenshot from the deuteranopia simulator in KMag.

IMHO we should be sure that our new default skin "fits all". For the other skins we may consider to do a very optimized for any visual disablements in one case, or just optimized for high fashion.
We should be clear about which skin solves which requirements. So that we later are aware of that and not destroy these features by accident.

How does Deere work for visual disablements in general?

We should not ship skins that are impractical for color blind users. It is not okay to only have one acceptable skin for color blind users and multiple choices for others. Fortunately, I do not think very much needs to be changed in any skin. In LateNight, it is the same red color used throughout. In Deere, I think it is only the red knob notches and the red metaknob link inversion button that do not work well. In Tango, the problem is also the red used in the skin. If we can figure out a different color instead of red, I think it will be okay. I'll try different shades of orange.

I don't think that's too bad, you have the contrast difference already so even in monochrome you would be able to see in the indentations. I could suggest maying the brighter bit at the end of the line on the knobs just a little bit bigger or brighter in colour but that's about it....

It's also acceptable to have on High Contrast skin, which would be perfectly viewable in monochrome/b&w, which I think it's worth checking for the most common red/green colour-blindness on the rest I'm not sure you need to make sure all of them are find right down to the contrast/brightness only level.
