This study examined the effects of lighting colour on emotional states and the effects of ethnicity on the impact of lighting colours on emotional states, based on the Mehrabian and Russell’s emotional state model measuring pleasure, arousal and dominance. It was hypothesised that there are significant differences in pleasure and arousal among six lighting colours: red, green, blue, yellow, orange and purple and that different ethnicities (i.e. Asian and Caucasian) can influence the effects of the six lighting colours on pleasure and arousal. To test the hypotheses, an experiment was conducted in a controlled lab using a colour-changing LED lighting fixture with 82 participants. The results revealed that there were significant differences in pleasure and arousal among the six lighting colours. Ethnicity had significant effects on the impact of lighting colour on pleasure but not on arousal. Blue was the most pleasant lighting colour and showed significantly higher pleasure than red and purple. Red was the least pleasant lighting colour and showed significantly lower pleasure than all other lighting colours. Asians found red and purple lighting significantly less pleasant than all other colours and tended to feel more unpleasant when exposed to red, orange and purple lighting than Caucasians.

这项研究基于Mehrabian和Russell的衡量愉悦，唤醒和主导地位的情感状态模型，研究了照明颜色对情绪状态的影响以及种族对照明颜色对情绪状态的影响的影响。假设在六种灯光颜色之间的愉悦和唤醒之间存在显着差异：红色，绿色，蓝色，黄色，橙色和紫色，并且不同的种族（即亚洲人和高加索人）可以影响这六种灯光颜色对愉悦和情绪的影响。唤起 为了检验假设，在可控制的实验室中使用具有82位参与者的变色LED照明灯具进行了实验。结果表明，六种照明颜色在愉悦和唤醒方面存在显着差异。种族对灯光颜色对娱乐的影响有显着影响，而对唤醒却没有影响。蓝色是最令人愉悦的照明颜色，并且比红色和紫色具有更高的愉悦感。红色是最不令人愉快的照明颜色，并且显示出比所有其他照明颜色低得多的愉悦性。亚洲人发现红色和紫色的照明明显比其他所有颜色都不令人愉悦，并且在暴露于红色，橙色和紫色的照明时比白种人更容易感到不适。
