I'm using win10 and dark mode.
A conflict is highlighted in blue, and the details in it are highlighted in a lighter blue.
I'd like to change all these colors.
I tried this meld.css, but it changed nothing.
I think I found it.
First, the dir gtksourceview-3.0 doesn't seem to be in use.
In my chosen scheme: meld-dark.xml
The background in
<style name="meld:replace" background="#000000" foreground="#1d59d6" line-background="#0053a6"/>
sets the conflict background.
The background in
<style name="meld:inline" background="#24527e"/>
sets the detail color.
