An experiment was conducted to extend the CIE whiteness metric under white sources having different CCTs. 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 tint limits were also verified and a limit of ±5T is proposed.
