The CIECAM02 colour appearance model differs from CIELAB in that it

  • A.produces a two dimensional rather than a three dimensional result
  • B.applies only to self luminous rather than surface colours
  • C.forecasts how a colour will look under stated viewing conditions
  • D.requires only the tristimulus values of the sample

Answer: C

Adapting luminance, surround and background all enter the calculation. It predicts brightness and colourfulness as well as lightness and chroma. Viewing conditions enter the calculation explicitly. Surround and adapting luminance both matter.
