Monochrome

Monochrome comes from the two Greek words mono (meaning "one"), and chroma (&chi;&rho;&omega;&mu;&alpha;, meaning "surface" or "the color of the skin").


 * 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.
