Hi, welcome to Chromatique!
This app lets you choose from a solid pitch-black screen to "save" your OLED screen, your favourite color, or a relaxing gradient animation.
Simultaneously, you can display your "Now Playing" metadata on-screen if you want to, e.g. to use it as minimalistic screensaver while listening to music.
I created Chromatique because I wanted a free and quick (and open-source) solution to completely turn off my OLED screen while listening to music and still get minimal music info.
Chromatique is open-source, feel free to contribute: https://github.com/mapluisch/Chromatique-for-tvOS
