You can make a Paint and setXfermode to XOR (PixelXorXfermode) and the
draw a solid rect on the bitmap. It will invert every bit - so when
you do it once more you are back to non-inverted. I am doing so in my
keyboard (http://www.maxikeys.com) to invert pressed keys - the room
between the keys have the color 50% grey, which will not change, when
being inverted.
