Abstract

Whiteness is an important quality parameter for surface colour industries. The CIE whiteness metric has been widely used but is known for shortcomings. For example, it cannot cover sufficient ‘white’ region in colour space and it should only be used for illuminant D65. In a psychophysical experiment, fifty samples were assessed using 2 scales. We investigated the influence of the spectral power distribution (SPD) of LED sources on whiteness perception. The results showed that the SPD can strongly affect the performance of whiteness metrics. Three versions based on CIE whiteness index were derived and they all gave similar degree of accuracy in predicting experimental data. The one with CAT02 performed quite well and is simple to use by applying the original CIE whiteness index under D65. The boundary limit can also be extended based on these data.
