Is your suggestion for improvement related to a problem? Please describe.
When creating a group I don't care what color the group has as long as it is clearly distinguishable from the other group colors.

Describe the solution you'd like
I'd like to have an option to assign a group color automatically. If the colors could be selected from a pallette with the greatest distance (eg HSV color space) would be an advantage. The manual assignment of colors should still be possible.
