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 and imaging. In the RGB model, when all three colors are combined at their maximum intensity, the result is white, while the absence of all three results in black. This model is widely used in various technologies, including televisions, computer monitors, and cameras, to accurately represent colors.
