1. A monochromatic object has a single color. In physics, the word is used more generally to refer to electromagnetic radiation of a single wavelength.
2. For an image, the term monochrome is usually taken to mean the same as black-and-white, but may also be used to refer to other combinations containing only two colors, such as green-and-white, green-and-black. It may also refer to sepia or cyanotype images.
3. In computing, monochrome has two meanings: it can mean having only one color which is either on or off, or also allowing shades of that color, although the latter is more correctly known as greyscale.
4. A monochrome computer display is capable of displaying only a single color, often green, amber, red or white, and often also shades of that color.
5. In the physical sense, no real source of electromagnetic radiation is purely monochromatic, since that would require a wave of infinite duration. Even sources such as lasers have some narrow range of wavelengths (known as the linewidth or bandwidth of the source) within which they operate.
6. Monochrome BBS is a bulletin board system.
7. Monochrome is an album released in 2006 by the American rock group Helmet.
