: The CIECAM97s and its revision, as a colour appearance model, were applied for a series of fabrics with different colours and depths to explain their colour appearance coordinates in similar viewing conditions.

Besides, the calculations were simpler for the revised version of CIECAM97s model while the results from the two models were the same.
