Abstract: Experimental research on the preference of a light stimulus still mostly relies on subjective feedback of participants which is why Electroencephalogram (EEG) recordings could meaningfully enrich those experiments by providing low-level psychological response data. There is little research on the influence of color on Visually Evoked Potentials (VEP) or the visual pathway regarding color perception and even less is known about visual processing with regards to color preference. This work shows that it is possible to both linearly separate EEG for differently colored stimuli as well as to spatially separate the VEPs with regards to different visual areas in the visual cortex all by employing a consumer-grade EEG device. High-luminance stimuli as well as the presented red stimuli produce higher peak VEPs than the produced lowluminance and green stimuli. Furthermore, the Color VEP seems to propagate from the primary visual cortex V1 towards the secondary visual cortex V2 which corroborates the assumptions of a hierarchical visual processing of color. This work was done in anticipation of further research which is meant to eventually find a link between color metrics, color preference and EEG features.
