RGB stands for Red, Green, and Blue. It is an additive color model where red, green, and blue light are added together in various ways to reproduce a broad array of colors. The primary use of the RGB color model is in electronic devices such as computer monitors, television screens, and digital cameras. These devices emit light to display colors. In an RGB system, each of the primary colors of light—red, green, and blue—is assigned a value representing its intensity. These values typically range from 0 to 255, where 0 means no intensity of that color and 255 means full intensity.

When all three primary colors are at full intensity (255, 255, 255), the result is white light. Conversely, when all three are at zero intensity (0, 0, 0), the result is black. Combinations of these three colors at different intensities create the wide spectrum of colors visible on display screens. For example, equal amounts of red and green light at full intensity, with no blue, produce yellow. The specific hue, saturation, and lightness of a color are determined by the precise combination and intensity of the red, green, and blue components. This model is fundamental to digital imaging and display technology.
