Setting / modifying background colour in Base table Relation Design window

Designing relationships between tables in Base brings up a screen with a grey background (#F2F1F0, it seems). However, this is the same colour as the “frame” around the tables. Here’s a little sample of what I see with LibO Base under Ubuntu 18.04:


With a complex database with many tables and relationships, having the same “frame” and “background” colour makes everything a littler harder to read.

I don’t see a way of setting a “custom” background colour … but I hope I’m missing something simple. I tried everything remotely relevant under Tools > Options... > LibreOffice > Application colours, but nothing there affected either the “frame” or the “background” of the “Relation Design” window.

Question - Is it possible to adjust, modify, the background colour of the “Relation Design” window in Base? I live in hope.

@dajare Don’t see any easy way of changing this. Have tried system (Mint 18.3), application & Mri to change without any results. Even glanced through Expert Configuration. May be in source or in a dialog xml file. Will post if found but not apparent as to where to start looking.

@Ratslinger - Thanks for looking into this. I played a bit in Ubuntu with system “theme” colours, but that didn’t get me very far (and is a bit sledgehammer-to-nut). If you/we don’t find something, perhaps this is worth an enhancement request, do you think?

Even if something is found (probably just a band-aid anyway) there should be an easy method to modify. Feel free to put in a request. Unfortunately, there are many more items I’d rather see fixed before this one.
