The RGB colour model mixes red, green and blue light to create colours on a computer screen. In the RGB model, the three colour components are additive and can have values ranging from 0 (black) to 255 (white). The CMYK colour model combines Cyan (C), Magenta (M), Yellow (Y), and blacK (K, also used for &quot; Key &quot; ) to create colours for printing. The four colours of the CMYK models are subtractive and are defined as percentages. Black corresponds to 100 % and white to 0 %.
