I am using Ubuntu 14.10 with the Unity interface and the Ambiance theme. I like this theme, and any other theme I've tried was much worse for me. However, one thing that really bothers me with this particular theme (it's not like that in others) is that the menus are hardly readable, with very dark background and foreground colors.
I would like to manually edit the CSS file(s) defining the theme and change the menu colors. Can anyone point me to the specific color definition (there are quite a few)?
A solution using a fine-tuning tool might also be acceptable, though generally I prefer to get in there and do it myself.
Note: I've read elsewhere that this might be a bug resulting from me also installing KDE. This doesn't seem to make sense, but even if that's really the case, uninstalling KDE is not an option as I sometimes use it too.
