Which color model is referred to as CMYK?

The CMYK color model refers to the colors cyan, magenta, yellow, and black. This model is primarily used in color printing and is based on the subtractive color mixing process. In this model, cyan, magenta, and yellow are the primary colors, and they combine to absorb (subtract) different parts of the spectrum of light. Black is added to enhance the depth and detail of the printed images, as combining the three primary colors can sometimes result in a muddy brown rather than a true black. This is why black is included in the model, leading to its designation as CMYK.

This understanding of color mixing is fundamental when working with print media, as it differs significantly from the additive color model used in digital displays, which typically includes red, green, and blue (RGB). The inclusion of black in the CMYK model is essential for achieving a wide range of tones and preserving quality in printed materials.
