An RGB keyboard has a backlight in keys which allows setting different colors to different keys. RGB keyboard uses a combination of Red, Green, Blue to create different colors. And like a LED screen that uses such an RGB combination, an RGB keyboard assigns different colors to a key. An RGB keyboard can significantly increase the accuracy of pressing the correct key. It is because users generally give separate colors to keys that they frequently use. The accuracy also increases by assigning a different color only to the letter keys of the keyboard.
