Kurzbeschreibung (Abstract)

Reddish cosmetics products (e.g. skin -tone powders or red lipsticks) are important for the LED lighting of beauty shops and TV or film productions. In our visual experiment, subjects had to assess their color preference, naturalness, and vividness impression of such cosmetics products viewed with seven different mult i-LED spectra of a six-channel LED illuminating system at 3200 K and 500 lx. It was found that1. a mult i-LED spectrum with a maximum color rendering index does not guarantee best visual color preference, naturalness or vividness assessments;2. a quantity describing object oversaturation (e.g. a color gamut index) is a better descriptor; and 3. if over-saturation exceeds a certain limit then observers will not prefer these reddishcosmetic products any more.
