CIELUV differs from CIELAB in that CIELUV

  • A.applies only to transmitting rather than reflecting samples
  • B.retains a chromaticity diagram with straight line mixing
  • C.uses a cube root rather than a linear lightness scale
  • D.requires no reference white point in its calculation

Answer: B

Correct answer: retains a chromaticity diagram with straight line mixing

CIELUV keeps the projective relationship to XYZ, so additive mixtures still lie on straight lines and a uniform chromaticity diagram can be drawn. That suits the display and lighting industries, where colours are added. CIELAB gives up the straight lines and is preferred for surface colours, where they are of no use.
