Personally, as a reasonably heavy math use, I'd hate to have a windows cluttered by differently colored insets all over.
You will not, because I will propose a background color that is the same as buttonbg; and if you are willing to go a step further, the attached patch implements mathhoverbg (the same as buttonhoverbg) so mathed will have the same hover behavior as InsetCommand. Try it yourself and let me know if you like it. Bo
