System Information
Operating system: Windows / Linux
Graphics card: dual Quadro 5000

Blender Version
Broken: 2.8+
Worked: ?

When you have light coloured bone groups and enable channel group colours in the dope sheet or graph editor the light coloured background makes the light text unreadable in the channel names.

To reproduce: assign bones to a bone group with a light colour, say yellow (as pictured, though it could be even worse). Enable Channel Group Colours in the preferences>animation tab.

Expected: text labels automatically turn a contrasting colour. You could get the perceptual brightness of the BG and scale the brightness of the text accordingly. A discussion about algorithms to do this here: https://stackoverflow.com/questions/635022/calculating-contrasting-colours-in-javascript

Observed: See image. The light coloured text is almost unreadable.

Thanks for the report, I can confirm the bad readability.
Here is a file with the bone and a bone group set:

Oh yes! You're right! It is already being handled in a design task. I will merge the reports.
