Monochrome wiki:
ething which is monochromatic has a single color. In physics, the word is used more generally to refer to electromagnetic radiation of a single wavelength.For an image, the term monochrome is essentially the same as black-and-white, but monochrome may be preferred to indicate that combinations such as green-and-white, green-and-black, etc., are not excluded. In computing, monochrome has two meanings: it can mean having only one colour which is either on or off, or also allowing shades of that colour, although the latter is more correctly known as greyscale. Thus it too has some ambiguity.
