The color of the diffs was changed in r107127 and r109932. This file https://github.com/huggle/huggle3-qt-lx/blob/master/huggle/Resources/Header.txt should be updated to match the current colors.
The CSS should be replaced by the content of https://git.wikimedia.org/blob/mediawiki%2Fcore.git/HEAD/resources%2Fmediawiki.action%2Fmediawiki.action.history.diff.css
