Correlated color temperature is widely used to describe colors of lights, but it has been questionable if it is well correlated to real perception. This study approached this issue with warm-cool feelings, that is, the same correlated color temperature would evoke the same level of warm-cool feelings. Since warm-cool feeling is widely accepted to correlate closely with hue, a psychophysical experiment was performed to collect visual data of lights in terms of both hue and warm-cool feelings. As a result, the hue and the warm-cool prediction models were, respectively, proposed. The proposed hue model has the same structure with CAM16 with new degree of adaptation considering the luminance and chromaticity and unique hue angle settings for lights. The warm-cool model can be used in conjunction with the hue model, which enables to assign the correlated color temperature based on the warm-cool feelings as a new calculation method for correlated color temperature that is expected to achieve a better visual resemblance.

一种基于暖冷相关色温计算的色调和暖冷模型

相关色温被广泛用于描述光的颜色，但它是否与真实感知良好相关一直存在疑问。本研究以冷暖感觉来解决这个问题，即相同的相关色温会唤起相同水平的冷暖感觉。由于冷暖感觉被广泛认为与色调密切相关，因此进行了一项心理物理实验，以收集灯光在色调和冷暖感觉方面的视觉数据。因此，分别提出了色调和暖冷预测模型。所提出的色调模型具有与 CAM16 相同的结构，具有新的适应度，考虑到灯光的亮度和色度以及独特的色调角度设置。暖冷模式可以与色调模式结合使用，
