I can't read the first line of a search result in the Message pane due to low contrast on ubuntu with dark theme (dark blue on black, see screenshot on https://github.com/geany/geany-themes/issues/40#issuecomment-1115851929) @carlos157oliveira explained here a way to change "Compiler"'s pane colors using CSS : how can tweak these CSS to change "Messages"'s pane colors instead of Compilers ?
