Colors in Mind: A Comprehensive Study on the Neurological Impact of Saturation

The perception of color is a crucial cognitive aspect that profoundly impacts cognition, emotions, and behaviour. Cool colors evoke comfort and relaxation, while warm colors stimulate and energize. This study explores how color saturation impacts brainwave patterns, using EEG signals and the MUSE BCI. Twenty-five participants, including 5 colorblind individuals, aged 18-60, viewed 10 colors on a computer screen at varying saturations. Analysis reveals distinct color effects on attention and diverse responses. Notably, saturated blue captures attention, while yellow and violet elicit a less pronounced response. Energy frequency band analysis shows varied stimulation levels across brain waves. The ERD/ERS complex indicates positive aspects, suggesting desynchronization during color observation and heightened neuronal excitement. The study underscores color's substantial role, offering insights into psychology. Frontal EEG measurements elucidate the influence of color saturation on physiological and perceptual responses.
