Research on visual comfort of color matching in space station experiment module

Considering the living environment, appropriate color adjustment has a positive effect on improving the visual comfort of astronauts, promoting their physical and mental health, and enhancing work efficiency. This article takes the Chinese space station experimental module as a prototype, and through simulation experiments, uses a method that combines physiological signals with subjective evaluation to compare the differences in the impact of 9 different color matching schemes on human visual comfort. The results showed that using 2-3 colors for pairing resulted in the highest visual comfort for people, and people were more willing to choose cool, white, or cool, warm, and white combinations. Among them, spaces using blue, green, and white combinations could help alleviate visual fatigue, while spaces using yellow, green, and white combinations could help people maintain or form a good psychological state. Finally, the experimental results were discussed, and prospects for the future development and construction of space stations were discussed.
