That's the method I use, by mapping these in my ~/.Xdefaults:

! Quick background-color toggles
URxvt.keysym.M-minus: command:\033]11;0\007\033]10;15\007
URxvt.keysym.M-equal: command:\033]11;15\007\033]10;0\007

Then Alt+- toggles to white-on-black, and Alt+= toggles to 
black-on-white (back to default).
