Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors. The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. The RGB color model (UK spelling: RGB colour model) is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors.
