The RGB color model is a system used to create colors by combining three primary colors: Red, Green, and Blue. Each color is represented by a value, typically ranging from 0 to 255, which indicates the intensity of that color. By adjusting these values, a wide spectrum of colors can be produced, making it essential for digital displays like computer monitors and televisions. In the RGB model, colors are created through additive mixing, meaning that when the three colors are combined at full intensity, they produce White. Conversely, when all colors are at zero intensity, the result is Black. This model is widely used in various applications, including photography, graphic design, and web development.
