“In Photoshop’s Duotone mode you can create monotones, duotones, tritones, and quadtones—grayscale images to which you add one, two, three, or four colors.”

“When using tritones or quadtones (in which three colours are blended together) all the secondary colours are mixed together.”

“The two colours need not be black and grey; computer duotones can be created from a greyscale original in any two colours; tritones use three inks and quadtones four.”
