The Additive Color Model is a method used to create colors by combining different light wavelengths. It primarily uses three primary colors: red, green, and blue. When these colors are mixed together in various intensities, they produce a wide range of colors. For example, combining all three at full intensity results in white light, while the absence of all three results in black. This model is commonly used in digital displays, such as computer monitors and televisions, where light is emitted directly. By adjusting the intensity of each primary color, devices can display millions of colors, making the additive model essential for modern visual technology.
