All of the following are outputs of a colour matching system EXCEPT

  • A.candidate recipes with predicted concentrations
  • B.a predicted reflectance curve for each candidate
  • C.predicted colour difference and metamerism index
  • D.the fastness rating of the resulting dyeing

Answer: D

Correct answer: the fastness rating of the resulting dyeing

The system predicts everything that follows from the reflectance curve - candidate concentrations, predicted curves, colour differences and metamerism indices. Fastness is a property of the dye and the substrate that must be looked up from the manufacturer’s data or tested, and it is one of the reasons the colourist reviews the candidates rather than taking the top-ranked one.
