Study on the influence of different color temperature and illumination environment on cognitive processing depth

Indoor lighting environment has an impact on people’s physiology, psychology, cognition, and other aspects, thus affecting people’s work tasks and work efficiency. This paper studies the effects of different color temperature and illumination conditions on cognitive processing depth. The experimental results show that different screen brightness has significant influence on information processing ability under three light environments: dark, white and yellow. The performance of tasks with different processing depth is different under different light environmental conditions. High brightness display and color matching style of night vision interface is recommended in dark environment. High brightness display is recommended in yellow light environment; In white light, medium brightness display and white interface matching style are recommended.
