RGB Color Model

The RGB color model is an additive color model in which the red, green, and blue primary colors of light are combined in varying amounts to reproduce a broad range of colors, with the name derived from the initials of its three primaries. It underlies the sensing, representation, and display of images in electronic systems such as televisions, computers, and cameras, and it had a theoretical basis in human color perception even before the electronic age. RGB is a device-dependent model: because different devices detect or reproduce a given RGB value differently, an RGB value does not specify the same color across devices without color management. Color printers are a notable exception among common devices, since they are subtractive devices that typically use the CMYK model rather than RGB.
