Font Color and Ownership Color Clash in Non user friendly way

[DanielHabenicht]

The user is confused in multiple ways:

• color does not apply
• displayed (as in written in the Color select Box) Color is not visible
• no obvious way to make it apply

The goal of this issue is to clear up the confusion:

1. Block the user from editing the color (stating "Please remove membership color before", maybe even providing a shortcut for it)
2. Just apply the color, not taking in account that text might get unreadable by having no contrast between ownership color and text color.

Which of the ways is the best?

This is even more confusing with

"padOptions": {
  "noColors": true,
}
