The study aims to investigate how the light source's correlated color temperature (CCT) affects a user's perceptual attributes, such as preference, naturalness, and vividness when viewing cosmetic color. Four standard light sources, including A, D65, TL84, and CWF, are tested in the study. As a result, the TL84 white light source can provide the best naturalness. The observers prefer light sources with low color temperature, and A white light source is more conducive to enhancing the vividness of cosmetic colors for both lipstick and eyeshadow color. The psychophysical experimental results can provide the best lighting design for makeup applications and be regarded as a reference for international lighting organizations to formulate the related standards.
