“…Most recently, Lin et al [17] analyzed the color preference in a restaurant, a retail display, and a supermarket, obtaining different results in each case study. Other studies, such as that by Hegde et al [18], demonstrate that the saturation of colors also varies depending on the age of the observer.…”

Daylight Spectrum Index: A New Metric to Assess the Affinity of Light Sources with Daylighting

The current scenario of colorimetry shows a wide variety of different metrics which do not converge in the assessment of the color rendering of light sources. The limitations of the Color Rendering Index have promoted the emergence of new metrics, such as the Color Quality Scale. As in the case of the previous metric, these new concepts are based on the analysis of the deviation of different color samples in a color space, contrasting the results with those obtained with a light source reference, which can vary depending on the color temperature. Within this context, the Daylight Spectrum Index is proposed. This new concept aims to determine the affinity with daylighting of electric light sources, comparing the resulting spectral power distributions of the lamps studied and that observed under natural light. The affinity of an electric light source with daylighting allows for lower energy consumption due to the better performance of human vision. The new metric proposed is evaluated following the results obtained from 80 surveys, demonstrating the usefulness of this new concept in the quantification of color rendering of LED lamps and the affinity of electric light sources with daylighting.

“…For example, the blue and white flower colors are perceived as the most relaxing, while orange, white, yellow, and red flower colors are deemed the most exciting [11]. Generally, people have different emotional responses to colors under different conditions of color saturation [25]. As urban color research progresses, a large number of existing studies on blue-green spaces emphasized the effects among landscape color, perception, emotion, and psychological processes.…”

“…Drawing upon the psychological process of human environment perception, the CER process can be similarly divided into four stages: color sensation, color association, color image cognition, and the ultimate CER. Based on previous studies on the influencing factors of visual landscape [25,26,28,33,36], this study introduced the color landscape as an object, the elderly as a subject, and the seasonal factors representing time, to examine the effects of these elements on CER. This study is dedicated to exploring the overall CER tendencies of the elderly, testing significant differences in CER between autumn and winter scenes, as well as examining the significant effects of individual factors and color characteristics on CER.…”

Addressing the emotional needs of the elderly in urban space design has increasingly become a vital concern. This study innovatively integrates emotional theories with the design of community outdoor spaces, thereby expanding the research on emotional categorization in urban spaces. At 8 community outdoor space sites in Yi Jie Qu, China, 330 elderly residents were randomly recruited to assess their color emotional responses (CER) to the color landscapes of these spaces. Based on the Affective Circumplex Model and Japanese Color Image Theory, a Color Emotion Circumplex was constructed to visually represent the overall emotional tendencies and significant positive emotions of the elderly. The second innovation of this research lies in exploring the driving factors behind positive emotional responses of the elderly, the primary user group of community outdoor spaces. We analyzed the significant differences in CER between autumn and winter scenes, employing variance analysis, correlation, and regression to investigate the substantial effects of individual factors and color characteristics on positive CER. The study discovered that the elderly exhibit a stronger CER towards clean and healthy emotions. Notably, CER was more pronounced in autumn scenes compared to winter. Furthermore, educational level, visit frequency, and color brightness positively influenced positive CER, whereas walking time from residence and the color area ratios of blue and gray negatively impacted CER. These findings not only provide a theoretical basis for age-friendly color design in community spaces, but also offer new perspectives and practical guidance for the international community planning and design domain. Our research underscores the importance of incorporating the emotional needs of the elderly into urban space design, offering novel theoretical and practical guidance for future urban planning and community design.
