RGB

RGB stands red, green and blue for the three basic colors. The fact that the basic colors in lights are different from the yellow, red and blue known from art lessons is due to the additive principle that is added. For lights that are marked with RGB, the color can be set and changed. Almost all mixed colors can then be made from these basic colors, which is also referred to with added color synthesis. RGB lighting is particularly suitable for decorative purposes with color dynamics in order to map color gradients and generate certain moods in the room.

The RGB color mixture is often supplemented with an additional white light source, which is then referred to as RGBW lighting (red, green, blue and white). This expansion creates a better white light color, but with LEDs, however, these basic colors are used for the production of white light.

In general, the RGB color mixture is used primarily for screens and LEDs, the latter is based entirely on this principle. If all three colors are put together, white light is created, these are all left out, so a black image is created. This RGB color mixture is only possible because of the way we humans see at all, since we have three so -called cones in the eye, which can perceive exactly these three basic colors red, green and blue. However, most other mammals do not have such three cones and therefore see differently.
