Abstract

Subjects rated the colour preference of a colourful object scene illuminated to 2000 lx by 28 different spectra from a four-channel LED light engine at different object saturation levels and different white points (3200 K, 4200 K, 5000 K and 5600 K). Mean colour preference ratings had a maximum at a moderate saturation level. The lowest correlated colour temperature (3200 K) exhibited lower preference ratings than the three higher correlated colour temperatures. The influence of saturation level was modelled by existing colour rendition measures and by the measure colour quality combining a colour fidelity index and an overall object colour object saturation measure taken from Part 4 of this work.
