Chromaticity coordinates x and y are obtained by

  • A.dividing X and Y by the value of Z alone
  • B.taking the logarithms of X and Y respectively
  • C.subtracting Z from both X and Y in turn
  • D.dividing X and Y by the sum of X, Y and Z

Answer: D

The normalisation removes the luminance and leaves only the colour quality. The third coordinate z follows since the three must sum to one. Two coordinates therefore suffice to fix a chromaticity. The third adds nothing new at all.
