The RGBox is an experimental game to teach fundamentals of additive color mixing theory.
As opposed to the behavior of pigments that get darker once mixed together (subtractive mixing), light colors get brighter once you increase the amounts of red, green, and blue in the mix. The RGBox is intended to give users intuition with this concept via a tangible experience.
The interface is composed by an LED strip and potentiometers. Within a given time, the user has to match an initial randomized color by adding or subtracting color amounts from a black pixel.
