The findings reveal a significant association between color code personality and depression, with white personalities exhibiting the highest levels of depression compared to red personalities. Additionally, anxiety was found to be positively correlated with depression. The study underscores the importance of understanding personality traits in developing interventions to address mental health concerns among university students.https://creativecommons.org/licenses/by/4.0Peer-reviewed Article
