How many colors are used in the CMYK color model?

The CMYK color model utilizes four colors: cyan, magenta, yellow, and key (black). This model operates on the principle of subtractive color mixing, where different percentages of these four inks are combined to produce a wide range of colors. In printing, colors are created by layering these inks on paper, with each color subtracting varying amounts of light, resulting in the desired shades.

Understanding his model is crucial for anyone involved in print design, as it directly relates to how colors are produced in physical media. The combination of these four colors allows for a broad spectrum of hues necessary for high-quality printed materials.
