Summary
This paper argues for a holistic approach to indoor environment design that considers how both object colors and light spectral qualities affect human emotions, performance, and health through photoreceptor mechanisms including ipRGCs. Practical implications suggest that lighting designers should account for extended temporal integration of light by ipRGCs and their peak sensitivity when specifying circadian-effective lighting for interior spaces.
Key Findings
- ipRGCs incorporate light signals over extended periods, resulting in increased sensitivity during prolonged light stimulation
- The paper advocates for holistic indoor design frameworks that integrate color, spectral composition of light, and non-visual biological effects on human health and performance
