Correlated color temperature (CCT) is a one-dimensional metric that aims to quantify the perceived visual quality of nominal white light sources. It is often used as a proxy for the color quality of light sources due to its ease of use. However, CCT lacks the accuracy in communicating color information for research purposes. Two light sources with identical CCTs can appear perceptually different, and these differences are not estimated by CCT due to the loss of information caused by reducing spectral power distribution of light sources into a one-dimensional metric. Using supplemental metrics in addition to CCT, providing the absolute spectral power distribution of light sources in graphical and tabular form, and documenting and accounting for potential confounding factors, such as chromatic adaptation, can increase the validity of research results, improve the repeatability of studies, and help address replication concerns.

相关色温 (CCT) 是一种一维指标，旨在量化标称白光源的感知视觉质量。由于其易用性，它通常被用作光源颜色质量的代理。然而，CCT 在为研究目的传达颜色信息方面缺乏准确性。具有相同 CCT 的两个光源可能会出现感知上的差异，并且由于将光源的光谱功率分布减少为一维度量会导致信息丢失，因此 CCT 无法估计这些差异。使用除 CCT 之外的补充指标，以图形和表格形式提供光源的绝对光谱功率分布，并记录和说明潜在的混杂因素，例如色适应，
