Additive colors are created by mixing light of different wavelengths. The primary additive colors are red, green, and blue (RGB). When these colors are mixed in different proportions, they can create a wide range of other colors. For example:

* Red + green = yellow

* Red + blue = magenta

* Green + blue = cyan

* Red + green + blue = white

Additive colors are used in a variety of applications, including television, computer monitors, and projector screens. In these devices, the primary colors are created by mixing light from different phosphors or LEDs. The relative intensities of the primary colors can be controlled to create a wide range of colors.

Additive colors are different from subtractive colors, which are created by mixing pigments or dyes. Subtractive colors work by absorbing certain wavelengths of light and reflecting others. The primary subtractive colors are cyan, magenta, and yellow (CMY). When these colors are mixed, they can create a wide range of other colors, including black.

The difference between additive and subtractive colors is important because it affects how colors are reproduced in different devices. For example, additive colors are used in television and computer monitors because they can be easily mixed to create a wide range of colors. Subtractive colors are used in printers and other devices that use pigments or dyes because they are more resistant to fading and can create a wider range of dark colors.
