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.
This is dealt with in the professional video world by converting the RGB signal into a component signal, also referred to as a YPbPr or YCbCr signal. The Y component of this signal is the black and white information contained within the original RGB signal.
