What is an important characteristic of CMYK colors?

The important characteristic of CMYK colors is that they are subtractive colors. This means that CMYK, which stands for Cyan, Magenta, Yellow, and Key (Black), works by subtracting varying wavelengths of light from white light. When these colors are combined in different proportions, they absorb specific wavelengths and reflect others, which is how we perceive the colors in printed materials.

In the context of printing, when you add more ink from these colors, you get darker and darker results, eventually reaching black when all inks are combined. This subtractive process contrasts with additive color systems, such as RGB, where colors result from adding light. The response of CMYK to light and its method of color combination makes it essential for any professional involved in graphic design or print production to understand.
