Which color in the CMYK model represents black?

In the CMYK color model, which is primarily used in color printing, 'Key' refers to the black component of the model. The 'K' in CMYK stands for 'Key,' and it is used to produce deep, dark tones in printed materials. The need for black ink in addition to cyan, magenta, and yellow stems from the limitations of combining the other three colors to create a true black. Instead, using black ink allows for richer contrasts and more precise detail in printed images.

The other colors in the CMYK model—cyan, magenta, and yellow—are the primary colors used in subtractive color mixing, but none of them accurately represent black. Therefore, recognizing 'Key' as the component representing black in this context is essential for color accuracy in printing practices.
