Chrooma Keyboard - RGB is a discontinued Android keyboard app that was known for its highly customizable RGB lighting features. While the app itself is no longer available on the Google Play Store, it was popular for allowing users to personalize the keyboard[SQ]s appearance with a wide range of colors and lighting effects. This personalization extended beyond just the background; it often included features to change the color of individual keys based on the app being used or even typing style. The "RGB" in the name refers to the red, green, and blue color channels used to create a broad spectrum of colors. Essentially, it was a keyboard app that aimed to provide a visually appealing and customizable typing experience.
