Cyan is a bright, lively greenish-blue. It is one of the cornerstones of the subtractive color model and, as a result, is hugely important in print.
Cyan combines well with its complement, red. You can also pair it with yellow and magenta—two other colors in the subtractive color model. Both of these combinations are bold and modern. For a more conservative color palette, combine cyan with darker shades of blue or with cool grays and whites. You can also create a monochromatic color palette with the vibrant hue, which is good for a background.
