I want to change the hard-to-read color scheme I see for meld (under Ubuntu 20.10.)

(I am using meld to highlight similarities between text, rather than differences. It turns out for mostly-different text, meld is still brilliantly useful but very hard to read under any of the color schemes.)

I have tried editing /usr/share/meld/meld.css (as described at https://wiki.gnome.org/Apps/Meld/DarkThemes) and it seems to make no difference.

I have tried creating a new mode /usr/share/meld/styles/meld-new-mode.xml and that new mode shows up in Meld/Preferences, and I can select it, but my edits to the .xml still do not change the text colors in meld.
