A catalogue of approximately 57,000 colours has been calculated, based on pigmented viscose rayon staple of 22 different colours. The catalogue is in two parts; the first provides the resultant colour of a blend of either two or three colours and the second enables match predictions to be made. The procedure is to measure tristimulus values X, Y , and Z on a colorimeter, look up these values in the catalogue, and obtain immediately one or more blends that will be approximate matches to the pattern. If this match is not good enough, the catalogue can be used to obtain a corrected recipe. Details are given of the calculation of the catalogue, and of factors that affect the limits of accuracy attainable when the catalogue is used in match prediction.
