Painting-based psychological analysis is a form of psychological intervention characterized by artistic and scientific qualities, which has gradually permeated the fields of mental health education and counseling. Color psychology, as a theoretical foundation, provides in-depth interpretation of emotional expression, personality traits, and psychological states reflected in artworks. To ensure both theoretical depth and practical value in painting-based psychological analysis courses grounded in color psychology, this article conducts a systematic analysis and study on the development of course content. The research shows that implementing strategies such as anchoring core theoretical points, designing diverse practical modules, and establishing a teacher training system can effectively address issues like imbalanced course content and the disconnect between theory and practice. This, in turn, promotes the standardized construction and professional development of painting-based psychological analysis courses.
