The environment has a great impact on the quality of learning, among which light has the most direct impact. Some studies have demonstrated that changes in lighting can affect students’ learning performance and emotions. This study aimed to examine correlated color temperature (CCT) impact on subjects’ emotions and study conditions. We used a TGAM module to measure Alpha, Theta, and Delta brainwaves. This study used CCT as a controlling factor and then estimated the relationship between individuals’ emotions and learning conditions with CCT values of 1000 K and 7000 K, respectively. The WS2812B device is used to control the CCT. According to our experimental results, subjects with a low CCT will have a better learning performance than the ones with a high CCT.
