Trying to figure out the correct setting for color in GUI

Quick question!
Which setting is for the marked edge (to the right) alone?
I want to adjust it to be similar to the upper tab edge.


Really… no one?

Hello - the basic colors are here:


It is the “UiPaintcolors.NormalBorder” color in advanced properties or “Windows border” color in Appearance/Colors.

Thanks John and Pascal…
It’s weird though… on my computer the rightmost tabs have a brighter line than the top ones…
I’ll have to check it out again…

OK, so i just noticed that there is a thin white line around the tab border…
Is this something that is removable/customizable?
If not… is this something that we can change for a one of the upcoming revisions? :wink:
