Influence of color on glare perception revealed when seeing the sun through colored glazing.

ABSTRACT: The influence of color on discomfort glare from daylight remains unknown, despite its known effects in electric lighting. This gap limits the ability to predict and mitigate glare in environments with colored glazing and filtered daylight. To address this, we conducted experiments in a controlled daylit office where 56 participants were exposed to four glare conditions induced by the sun visible behind the colored glazing. The conditions differed only in glazing color (red, blue, green, and neutral) towards the sun while having similar visual transmittance resulting in similar glare metrics across colors. Results revealed a strong influence of color with red glazing leading to the highest reports of glare, closely followed by blue, while green and neutral were perceived as least disturbing
