Colors: Ability to use Hex colors and expressions all over the Editor

We can use Hex colors in Format Rules.

I would like to be able to use Hex colors also in:

  • Column type “Color” [actually we are limited to these colors: “blue”, “green”, “orange”, “purple”, “red”, “yellow”, “black”, “white” (which is light gray)]
  • With this we could use it also for Calendar
  • Brand - Color theme

Also I would like to use Expressions in the every Color setting.

This would give us the possibility, to use a color code for every user.
Or the User could set his own color via the UserSettings.
