Perceived and measured colour attributes under different sources

Subjective responses to different light sources. A study on light preferences and comparison of standard light measures with human individual estimates

The experimental research here described investigates how people perceive different light sources that have same CCTs and illuminance values on a visual task. The results show that photometric quantities like illuminances and CCTs fail to guarantee users comfort, because parameters like SPD of the light source and its technology heavily influence people's perception of an environment.
