If your home could do with a paint pick-me-up, either indoors or out, pick up a brush and roller before you list. Be forewarned: Home sellers often confront color conundrums. Paint a room a shade too dark, and it can seem small and cramped. Paint a room a stark white, and it will feel cold and uninviting. Choose light, neutral colors with wide appeal, as bold hues can scare off buyers.
