Color Clock Wallpaper is a free Android live wallpaper developed by Steren Giannini. As the name implies, it changes the color of your smartphone's background according to the time. This personalization app helps you tell the time without having to look at the clock.

The app has a unique concept that is both simple and innovative. You can train your brain to remember the color of the background of your smartphone after having checked it. The tint of the background color corresponds to a time, which makes it easy to tell time. For instance, at 00 minutes the background color is red, at 07 minutes it's yellow, at 15 minutes it's green, at 30 minutes it's turquoise, at 40 minutes it's dark blue, at 50 minutes it's purple, and at 59 minutes it's red again.
