Abstract Correlated color temperature, which describes the chromaticity characteristics of a radiating source, is different from its thermodynamic temperature derived from primary spectrum pyrometry. However, establishing their mathematical relationship is feasible. Therefore, the authors theoretically analyzed the variation rule of the correlativity difference between the correlated color temperature of the source and its thermodynamic temperature with the emissivity parameter. And the authors gave the corresponding numerical simulation results. The above theoretical and numerical discussions will make it possible that a colorimeter used to measure the correlated color temperature serves as a pyrometer to realize the measurement of the thermodynamic temperature.
