Cyan, magenta, and yellow are the three subtractive primary colors used in printing.

In color printing, the shade of cyan called process cyan or pigment cyan is one of the three primary pigment colors which, along with yellow and magenta, constitute the three subtractive primary colors of pigment. (The secondary colors of pigment are blue, green, and red.) As such, the CMYK printing process was invented in the 1890s, when newspapers began to publish color comic strips.

Process cyan is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure cyan ink. A typical formulation of process cyan is shown in the color box at right. The source of the color shown at right is the color magenta that is shown in the diagram located at the bottom of the following website offering tintbooks for CMYK printing: [1].

Red, green and blue lights, representing the three basic additive primary colors of the RGB color system, red, green, and blue. Cyan light is composed of equal amounts of green and blue light.

The web color cyan, shown at the right, is one of the three secondary colors in the RGB color model, used for creating all colors on a computer or television display by mixing various combinations of red, green and blue light. The X11 name for this color is cyan; the HTML name for the same color is aqua. They are both composed of the same mixture of blue and green light, and are exactly the same color.
