Colorimetric matching is employed under a series of virtual illuminants to produce more controllable and equalised colour‐difference results under multiple illuminants. A method based on weighted principal component analysis of different artificial lights and the weighted mean is used to create a series of virtual illuminants. The weights were selected in a manner to create the virtual illuminants that benefit from the impact of a given illuminant, while the effects of other light sources on the formation of desired illuminants were also considered. The generated virtual illuminants were implemented in a colorimetric colour‐matching trial. Using this method, by choosing suitable weights for different lighting conditions, more balanced colour‐difference values were presented in the data set than was expected. The advantages of the suggested method were evaluated by the matching of a collection of 135 woollen samples under different virtual illuminants.
