The design of the light environment plays a critical role in the interaction between people and visual objects in space. Adjusting the space's light environment to regulate emotional experience is more practical for the observers under lighting conditions. Although lighting plays a vital role in spatial design, the effects of colored lights on individuals' emotional experiences are still unclear. This study combined physiological signal (galvanic skin response (GSR) and electrocardiography (ECG)) measurements and subjective assessments to detect the changes in the mood states of observers under four sets of lighting conditions (green, blue, red, and yellow). At the same time, two sets of abstract and realistic images were designed to discuss the relationship between light and visual objects and their influence on individuals' impressions. The results showed that different light colors significantly affected mood, with red light having the most substantial emotional arousal, then blue and green. In addition, GSR and ECG measurements were significantly correlated with impressions evaluation results of interest, comprehension, imagination, and feelings in subjective evaluation. Therefore, this study explores the feasibility of combining the measurement of GSR and ECG signals with subjective evaluations as an experimental method of light, mood, and impressions, which provided empirical evidence for regulating individuals' emotional experiences.
光环境的设计在人与空间中视觉物体的相互作用中起着关键作用。在照明条件下，调节空间的光环境以调节情绪体验对观察者来说更具实际意义。虽然照明在空间设计中起着重要的作用，但彩色灯光对个体情绪体验的影响仍不清楚。本研究结合生理信号（皮肤电反应（GSR）和心电图（ECG））测量和主观评估，检测了观察者在四种照明条件（绿色、蓝色、红色和黄色）下的情绪状态变化。同时，设计了两套抽象和现实的图像，讨论了光与视觉物体之间的关系及其对个体印象的影响。结果表明，不同的光色对情绪有显著影响，红光的情绪唤醒最显著，其次是蓝光和绿光。此外，GSR 和 ECG 测量值与主观评估中的兴趣、理解、想象和感觉评估结果显著相关。因此，本研究探讨了将 GSR 和 ECG 信号测量与主观评估相结合作为光、情绪和印象的实验方法的可行性，为调节个体情绪体验提供了经验证据。
