摘　　要：在考察现有相关色温的定义及在CIE 1960UCS、CIE 1976UCS和CIE 1976LAB 3种不同均匀色品图中计算值的不一致性基础上,提出了一种基于色调维度来规范计算相关色温的方法。该方法借助孟塞尔表色系统,建立色温与色调的对应关系,忽略饱和度对色温的影响,重构了3个色品图的等色温线。通过与传统相关色温计算方法比较,该方法具有物理意义更明确、在不同色品图中的计算结果一致性更好的优点。The definition of correlated color temperature and the contradiction of correlated color temperature in three different uniform chromaticity diagrams （ CIE 1960UCS, CIE 1976UCS and CIE 1976LAB ） 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.
