Abstract The definition of correlated color temperature and the contradiction of correlated color temperature in three different uniform chromaticity diagrams(CIE1960UCS, CIE1976UCS and CIE1976LAB) are investigated, and a new method based on single-dimension of hue is proposed. The corresponding relation between color temperature and hue was established in the Munsell color system, and the new iso-temperature lines in three uniform chromaticity diagrams are delineated by ignoring the influence of saturation on color temperature. By comparing the new method for correlated color temperature with the traditional method, the physics meaning of the new method is clearer, and low difference is existed in the results from different chromaticity diagrams.
