Color / Adjust / CMY, CMYK

The RGB model is based on three colour components (red, green, blue). These colours are characterized by the fact that the human eye has the highest sensitivity for their wavelengths (630nm, 530nm and 450nm). The RGB model works on the principle of additive colour mixing. The principle is based on the fact that three light beams, dark blue, deep red and deep green, combine to produce a bright, brilliant white light. All monitors, TV screens, etc. work on this model.

The CMY (cyan, magenta, yellow) model works on the principle of subtractive colour mixing. Unlike the RGB model, which is essentially based on light emission, it is based on light reflection. While additive mixing actually produces pure black (absence of light), subtractive mixing does not produce pure black. The CMY model is therefore usually enriched with a fourth black component. This results in a CMYK model. Most printers work in CMYK mode.
