Yellow

Yellow is one of the four primary colours used in the CMYK colour model, used extensively in colour printing.

The acronym stands for Cyan, Magenta, Yellow, and Key (black). The Yellow in CMYK is subtractive, meaning that it absorbs all colours of light except for yellow, which it reflects to your eye.

In printing, combining yellow with cyan produces a green tint, and with magenta, a red hue is obtained.
