Relationships are investigated between concentration changes in multi‐dye recipes and colour changes. Two methods are examined for predicting colour changes associated with small changes in dye concentration around ten colour centres. A synthetic reflectance curve generator and commercial match prediction system are used to generate the recipes. This simulates a dyeing process of zero variability and isolates the variables associated with the dyes. A matrix method is introduced to calculate AE for a given recipe concentration change in one or more dyes, possibly moving in opposite directions. The results are related to dye standardisations of ±2.5%, 5% and 10% strength. The matrix method is confirmed using a manual match prediction program.
