Lighting Preferences (06-25-19)

Huang and colleagues studied preferences for different lighting conditions.  They investigated  “the correlation between the perceived whiteness of lighting and the corresponding colour preference of observers. . . . meta-analysis results confirm our former statement that people prefer whiter illumination. . . . it was further demonstrated that for the scenarios with multiple correlated colour temperatures ranging from 2500 K to 5500 K people indeed preferred perceptually whiter light chromaticities, while for correlated colour temperatures higher than 5500 K it seemed that they appeared too cold to be preferred.”
