According to Apple Inc., the RGB signal is the standard signal for most computer graphics and video files. It is named for the colors red, green and blue. These colors, in certain combinations and intensities, can create any other color. RGB also supports grayscale, ranging from black to white.
In additive color models such as RGB, white is the additive combination of all primary colored lights, while black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, while black results from a full combination of colored inks.
