GUI in InDesign

I recently changed the theme colour in InDesign to dark; having grown up with the light theme I just fancied a change. I notice that some highlighted items are highlighted in orange, and I would like to be able to change that.

After a bit of digging in the Preferences I found that this is called ‘User Color’ but I can’t see how to redefine it.


The User color is only for notes in InDesign not for the GUI.

I can’t find any InDesign-perpetrated orange highlighting. Can you give some specific examples of where you’re seeing that?
