INFLUENCE OF SPECTRAL POWER DISTRIBUTION OF LIGHT SOURCES ON THE COLOUR APPEARANCE OF GONIOCHROMATIC COLOURS

摘要

The purpose of this work is to evaluate how the colour appearance of a goniochromatic set of coloured samples varies in front of the spectral power distribution and measurement geometry of two different lighting booths. The two lighting booths compared in this work were the Gonio-Vision-Box® (GVB) and the Byko-spectra effect® (BSE). Both use different D65 simulators and were designed to cover the most of geometric positions source-observer available, which can be measured in the current multi-angle-spectrophotometers. Due this, an additional purpose is to how the colour appearance of a goniochromatic sample varies using real light sources in both cabinets in front of D65 illuminant estimating the inconstancy color index for some measurement geometries.
