Heh! WHATEVER color you use, mask off the painting area from the rest of your house with plastic over the doors, etc. I sprayed a 180 reef tank about 10 yers ago with royal blue Krylon aerosols and still find blue paint dust occasionally on the top of window frames, doorways, etc. in that house (it's a rental now). Took an entire weekend of dusting and washing and wiping to clean up windows, cabinet doors, picture frames, etc...
