Certain Colors In Interactive Mode Can't Be Changed

[IsaacTheKind]

Describe the bug
Certain colors in interactive mode can't be changed.

To Reproduce
Change all the colorable regions to red (for debugging purposes, not because this is a desirable theme). Notice some areas are not red.

Expected behavior
All regions should be able to be colored as desired, we shouldn't be stuck with colors we don't want for certain regions.

Screenshots
I will show below what happens when all colors are set to red. whatever isn't red is not configurable as far as I can tell.

OS, version, khal version and how you installed it:

• The output of khal --version: khal, version 0.13.0
• Installation method: Nix packages
• python version: none
• OS: NixOS
• Your khal config file (while everything is red for debugging):

Additional context
Particularly frustrating is the blue on the currently-being-inputted region when I add an event, makes things utterly illegible in the very field I need to see as I type.

I have always had the same issue. I'm surprised that this has not been fixed after several years. :/
