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.
RGB is a device-dependent color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual R, G and B levels vary from manufacturer to manufacturer, or even in the same device over time.
