Informing on the impact of electric lighting and coated glazing on Colors in complex Architectural Scenes

Abstract

The ultimate goal of the study is to predict people’s preference for color shifts, in a context of architecture. As a first step, a color graphic icon providing descriptive information about color content and color shift is developed. It is a projection of the color content of each studied indoor scene (before and after change of illuminant and/or glazing) in PT plane of IPT color space after application of iCAM06 algorithm. For communication and interpretation, the color space is splitted into six color bins. First validation works (color listing and color composition experiments) highlighted that bin boundaries have to be modified to better match people perception
