Research on Dynamic Color Emotional Design Method for Smart Products

ABSTRACT Color plays a critical role in the visual communication of products, significantly shaping user perception and emotional response. With the rapid proliferation of smart products, dynamic color—enabled by features such as breathing lights and interactive displays—has emerged as a new form of emotional expression, yet current research predominantly focuses on inherent color. This study proposes a dynamic color emotional design framework specifically tailored for smart products by integrating neurophysiological and behavioral insights. An EEG‐based experimental paradigm is developed to quantitatively assess users' emotional responses to combinations of inherent and dynamic colors. Using dynamic video stimuli rather than static images, the study enhances emotional elicitation and data reliability. Experimental results show that both hue and saturation affect emotional evaluation, with colors like cyan and green eliciting more relaxed feelings and purple inducing tension. EEG analyses reveal that emotional states are reflected in characteristic changes across δ, α, and β frequency bands, particularly in the temporal and parietal lobes. This research provides a new perspective for the emotional design of dynamic color in smart products and offers empirical evidence for optimizing visual interaction. The findings support user‐centered design in contexts such as household electronics, enhancing both emotional engagement and product experience.
