Computer colour matching predicts

  • A.the colourant concentrations needed to reproduce a target colour
  • B.the colour that a given recipe will produce once it is applied
  • C.the price at which a dyed fabric should be sold
  • D.the observer who will best judge the resulting match

Answer: A

Correct answer: the colourant concentrations needed to reproduce a target colour

The system works backwards from the target: given a measured standard and a calibrated set of colourants, it computes what concentrations of which dyes or pigments will reproduce it. Predicting the colour of a known recipe is the forward problem, which is the easier half and is used inside the calculation.
