Abstract

We have performed spectroradiometric color measurements at different positions on the floor of two lights booths under two light sources. Uniformity provided by these light booths is enough acceptable for most practical color applications involving relative measurements (e.g. CIELAB coordinates), but not for absolute measurements (e.g. tristimulus values or illuminance). Averge color inconstancy indices are lower than 0.6 CIE94 (1.0 CIELAB) color-difference units.
