Hi Michael,

Yes, the Grid color rectangle, when it shows up, is the custom color. (Similarly for Accented Grid color rectangle.)

Maybe the Background rectangle color should mimic the Grid rectangle color behavior?

I just stumbled across the behavior while mimicking MoI5 dark theme with Dino's MoI.css for MoI4.
The dark MoI4 looks a lot like the MoI5 dark theme, with some "minor" differences.
The dark themes seem easier on the eyes, at times...

I have not been doing "custom colors", except as these tests, and can always look up the hex numbers in the Theme interface.

I thing/guess that the background rectangle color should match whatever the current custom number is...
