Addition of colors

The additive color method describes how colors are created by combining different primary color light sources. The primary colors used in the additive method are red, green and blue (RGB in English). When these primary colors are combined in equal proportions, they produce white light. If one increases the proportion of one of the primary colors in relation to the others, the light produced will have a corresponding hue. For example, if we increase the proportion of red in relation to green and blue, the light produced will be magenta in color. The additive color method is used in many areas that use light sources, such as the display of computer monitors, televisions, projectors, traffic lights, vehicle lights, and stage lights. Colors are usually created using light emitting diodes (LEDs) or liquid crystals (LCDs) which can produce different colors by adjusting the proportions of red, green and blue light.
