If your ceiling is a darker color the decals will be visible by day, but will still glow all night long. - Room must be very Dark at night! Make your ceiling appear as black as possible at night by removing all extra light sources and your glow in the dark stars and decals will look amazing. - NO UV BLACK LIGHTS are required, but are recommended for best effect.
