Part of the Multimedia and graphics glossary:

In graphic design, a duotone is an image composed of two colors. A duotone image can be used on a Web page to economize on file size as well as to give the image an artistic, retro look. A duotone is created by overlaying a color (such as blue or red) on a grayscale image.
