Adjusting the space\u2019s 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\u2019 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\u2019 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\u2019 emotional experiences.<\/jats:p>","DOI":"10.3390\/s23115322","type":"journal-article","created":{"date-parts":[[2023,6,5]],"date-time":"2023-06-05T02:57:47Z","timestamp":1685933867000},"page":"5322","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Affective Impressions Recognition under Different Colored Lights Based on Physiological Signals and Subjective Evaluation Method"],"prefix":"10.3390","volume":"23","author":[{"given":"Xing","family":"Xie","sequence":"first","affiliation":[{"name":"School of Art and Design, Guangdong University of Technology, Guangzhou 510000, China"}]},{"given":"Jun","family":"Cai","sequence":"additional","affiliation":[{"name":"School of Art and Design, Guangdong University of Technology, Guangzhou 510000, China"},{"name":"Academy of Arts and Design, Tsinghua University, Beijing 100086, China"}]},{"given":"Hai","family":"Fang","sequence":"additional","affiliation":[{"name":"School of Art and Design, Guangdong University of Technology, Guangzhou 510000, China"}]},{"given":"Beibei","family":"Wang","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Nanophotonic Functional Materials and Devices, School of Information and Optoelectronic Science and Engineering, South China Normal University, Guangzhou 510006, China"}]},{"given":"Huan","family":"He","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Nanophotonic Functional Materials and Devices, School of Information and Optoelectronic Science and Engineering, South China Normal University, Guangzhou 510006, China"}]},{"given":"Yuanzhi","family":"Zhou","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Nanophotonic Functional Materials and Devices, School of Information and Optoelectronic Science and Engineering, South China Normal University, Guangzhou 510006, China"}]},{"given":"Yang","family":"Xiao","sequence":"additional","affiliation":[{"name":"School of Physics and Telecommunication Engineering, South China Normal University, Guangzhou 510006, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9049-294X","authenticated-orcid":false,"given":"Toshimasa","family":"Yamanaka","sequence":"additional","affiliation":[{"name":"Faculty of Art and Design, Tsukuba University, Tsukuba 305-8577, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7844-8417","authenticated-orcid":false,"given":"Xinming","family":"Li","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Nanophotonic Functional Materials and Devices, School of Information and Optoelectronic Science and Engineering, South China Normal University, Guangzhou 510006, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1145\/3132027","article-title":"Mediated atmospheres: A multimodal mediated work environment","volume":"1","author":"Zhao","year":"2017","journal-title":"Proc.
