Research Design Connection: Light Color and Thinking
Weitbrecht and colleagues confirmed the differential implications of experiencing warm or cool light. Concentration and creativity were tested under three colors of light (3000K [warmer], 4500K, 6000K [cooler]) at the relatively high intensity of 1000 lux. The researchers determined that “creativity was better under warm light (3000 K) than under colder light (4500 K, 6000 K). Concentration was best under cold light (6000 K). W. Weitbrecht, H.
