The ruby reds and the strong blues of the stained glass windows of Romanesque and Gothic cathedrals are some of the most magnificent pieces of craftsmanship mankind has produced. According to our knowledge, no colorimetric attempt has been made to understand the visual impression produced by them. Modern colour‐appearance models permit the description of the colour impression produced by chromatic stimuli under changing adaptation conditions. In the present article, an attempt is made to model the visual situation and to use the colour‐appearance model developed by Nayatani and co‐workers for colorimetrically describing the observed effects. In model experiments, “extra brightness” was found when changing the direction of view from the dark surrounding to the well lit stained glass window. Calculations based on the Nayatani model yielded similar extra brightness and extra colourfulness, in good agreement with visual observations.
