The best formulas for predicting mean perceived small colour differences of industrially produced coloured goods have an average accuracy of about 65%. This should be considered unsatisfactory. Factors that influence accuracy are discussed in this paper and a proposal is made for determining if the accuracy can be significantly improved as a preliminary step toward developing more reliable data and a formula to predict it.
