This report describes the preparation of a reference colour tile, designed specifically for the calibration of colorimeters used to measure the colour of tomato paste. The homogeneity of the batch of tiles is discussed, and the results of a study which confirms the stability of the tiles are presented. Details are given of the procedure used to establish the certified values for individual tiles. The results of a cooperative study in which 44 European laboratories compared colorimeter measurements with and without a reference tile are also discussed, and the advantages of using the tile are demonstrated.
