Colors for computer monitors are often described using ordered triples. One model, called the RGB system, uses red, green, and blue to generate all colors. The figure describes the relation- ships of these colors in this system. Red is (1, 0, 0), green is (0, 1, 0), and blue is (0, 0, 1). Since equal amounts of red and green combine to form yellow, yellow is represented by (1, 1, 0). Similarly, magenta (a deep reddish purple) is a mixture of blue and red and is represented by (1, 0, 1). Cyan is (0, 1, 1), since it is a mixture of blue and green.

Another color model uses cyan, magenta, and yellow. Referred to as the CMY model, it is used in the four-color printing process for textbooks like this one. In this system, cyan is (1, 0, 0), magenta is (0, 1, 0), and yellow is (0, 0, 1). In the CMY model, red is created by mixing magenta and yellow. Thus, red is (0, 1, 1) in this system. To convert ordered triples in the RGB model to ordered triples in the CMY model, we can use the following matrix equation. In both of these systems, color intensities vary between 0 and 1.

In the RGB model, rust is (0.552, 0.168, 0.066). Use the matrix equation to determine the mixture of cyan, magenta, and yellow that makes rust in the CMY model.
