Eventually, 60 eligible articles were reviewed and included in this study. Results: Initially, 312 articles were identified out of various databases, and 123 studies fulfilled the inclusion criteria. On the other hand, 63 articles were excluded from the study due to a lack of experimental studies, and 60 articles were selected for final review. The factors that were emphasized in the studies included selective attention (n=6), alertness (n=3), sport performance (n=4), intellectual performance (n=7), aggressiveness/dominance evaluation (n=7), caution/avoidance (n=7), attraction (n=6), store/company evaluation (n=5), eating/drinking (n=7), memory (n=4), arousal (n=2), and time perception (n=2). The results also revealed that color had a significant effect on cognitive functions, including selective attention, alertness, sports performance, intellectual performance, aggressiveness/dominance evaluation, caution/ avoidance, attraction, store/company evaluation, eating/drinking, time perception, memory, and arousal. Conclusion: Color should be considered one of the main ways to promote mental health, perception, and behavior of people.
