Techopedia Explains RGB Color Model

The RGB color model is based on a the science of the human eye perceives light and translates it into brain waves. This model is extremely common for TV and video displays, video game console displays, digital cameras and other types of light-based display devices.The RGB model is as an “additive” model: as colors are added, in the form of light, the result becomes lighter. For instance, the full combination of red, green and blue produces white.

An alternative model to the RGB model is the CMYK model, which is used for color printing. This model uses the colors cyan (C), magenta (M), yellow (Y) and black (K), which is called the “key.” Whereas RGB is additive, CMYK is subtractive. This is because the CMYK system uses colored inks to mask colors on a white background and “subtracts” brightness from that white background.
