Have you ever wanted to see what it's like to be under a black light? Now you can! The Black Light app is the perfect way to play in the dark.

With this blacklight simulator, your phone screen will look just like a real black light. You can select the tone of color that you want, the time that you want the screen to be active, and the brightness of your screen. All these settings are for fun and don't actually produce any black light—they just mimic the color of one.

With Black Light, you can have your very own fluorescent rainbow.
