Effects of colored lights on an individual's affective impressions in the observation process

Abstract

The lighting environment has an important influence on the psychological and physical aspects of a person. On certain occasions, reasonable lighting design can regulate people's emotions and improve their feelings of comfort in a space. Besides, specific lighting can create a specific atmosphere according to space requirements. However, in the study of an individual's affective impressions, there is still some uncertainty about how colored lights affect an individual's moods and impressions toward visual objects. This research improves the understanding of the emotional impact of colored light in space. To better understand the lighting environment in the observation process, the project studied the effects of four groups of lights (green, blue, red, and yellow) on the participants' moods and impressions. Participants watched two sets of visual images under four different lighting conditions and provided feedback on their emotions and evaluations through the Multiple Mood States Scale, Two-Dimensional Mood Scale, and Semantic Differential Scale. The results show that different colors of light have a significant effect on mood, and red light can arouse emotional changes to calm, irritated, relaxed, nervous, stability, and pleasure. At the same time, different colors of light have a certain relevance to participants' impressions and this provides further research value for the design of the colored light environment in an individual's affective impressions. Therefore, this study discusses the feasibility of colored lights as a display method, which has potential application prospects for constructing different space atmospheres.

Immediate effects of lavender soy wax candle on autonomic nervous system, stress, and reaction time in adolescents

“…Producing the light by candle warmer may create room ambience and consequently enhance feelings of relaxation. In this study, the light-yellow color was autonomic generated by candle warmer may help to reduce irritated feelings and resulting in cozy and relaxing atmosphere [22].…”

“…This may be due to the scent of the organic soy wax candle blended with lavender oil to create a relaxing atmosphere in the experimental group [14]. Also, the autonomic lightyellow color produced by the candle warmer may help to lessen agitated feelings and create a warm and comforting environment [22].…”

The influence of cognitive load and vision variability on postural balance in adolescents with intellectual disabilities

“…Besides, the psychological impact of visual stimuli should be considered. Colors and visual stimuli have been shown to influence mood, arousal levels (55). Positive affect induced by visually stimulating environments may lead to increased motivation and engagement in postural tasks, potentially enhancing postural balance (56).…”

Millennial experience through the utilization of feature technology in coffee shop interior design

“…Technology features can help improve the aesthetics of space in interior design can create a more attractive and beautiful atmosphere. Some technological features that can be applied to interior design to improve the aesthetics of space include: LED lighting systems are features that can help create different atmospheres and strengthen design elements such as color [36] , textures, and patterns so as to improve the aesthetics of the room. Projection System as one of the superior technologies that displays digital art with images, drawings, and 3D imagery to be projected on walls or ceilings, thus creating beautiful and creative works of art [37] .…”
