black and white

black and white idiom
  1. A monochromatic picture, drawing, television image, computer monitor, or film, as opposed to one using many colors, as in Photos in black and white fade less than those taken with color film. [Late 1800s]
  2. Also, black or white. Involving a very clear distinction, without any gradations. For example, He tended to view everything as a black and white issue—it was either right or wrong—whereas his partner always found gray areas. This usage is based on the association of black with evil and white with virtue, which dates back at least 2,000 years. [Early 1800s] Also see gray area.
  3. in black and white. Written down or in print, and therefore official. For example, The terms of our agreement were spelled out in black and white, so there should be no question about it. This term alludes to black ink or print on white paper. Shakespeare used it in Much Ado about Nothing (5:1). [Late 1500s]
