EFFECTS OF CHROMATICITY DIFFERENCE FROM PLANCKIAN LOCUS <i>d_uv</i> OF LIGHTING ON TINTED COLOUR OF ILLUMINATION AND BRIGHTNESS IN SPACE (PART 2): EXPERIMENT USING A SCALE MODEL WITH NON-UNIFORM LUMINANCE DISTRIBUTION

Abstract

The purpose of this study is to identify the effects of chromaticity shift from the Planckian locus duv on the perception of the tinted colour of illumination and the spatial brightness. All 240 conditions with 3 levels of the illuminance, 4 conditions of the correlated colour temperature, 5 levels of duv and 4 patterns of interior reflectance including non-uniform luminance distribution were experimented.
