Lisäysvärimallissa

Lisäysvärimallissa, often translated as additive color model, describes a way of creating colors by mixing lights of different wavelengths. When you combine lights in this model, the resulting color is lighter than the original colors. This is in contrast to subtractive color models where mixing pigments results in a darker color. The primary colors in an additive color model are red, green, and blue. When these three primary colors of light are mixed together in equal proportions, they produce white light. Mixing two primary colors in an additive model produces secondary colors. Red and green light mixed together produce yellow. Green and blue light produce cyan. Red and blue light produce magenta.

The additive color model is fundamental to how we perceive color on electronic displays such as televisions, computer monitors, and mobile phone screens. Each pixel on these displays is typically composed of red, green, and blue sub-pixels. By varying the intensity of each of these sub-pixels, a wide spectrum of colors can be generated. For example, a pixel that is fully red, with no green or blue, appears red. A pixel that is a combination of full red and full green light appears yellow. A pixel with no light emitted from any of its sub-pixels appears black. The additive nature means that the more light is added, the brighter the color becomes, eventually reaching white when all primaries are at their maximum intensity.
