The next time you're painting a room, unscrew your light switch plates and try this tip—your future self will thank you.
Paint like normal with the plates off. But just before it's time to screw 'em back on, slap the back of the plate with a piece of painter's tape (or masking tape) and jot down the room's paint color name and product number.
If you ever need to make touch-up paint jobs down the line, it will be easy to match the color again. You could even tape a section of the paint chip to the reverse of the plate.
