This study investigates the influence of plant landscape colors on the quality of life of college students at Sichuan Vocational College of Health and Rehabilitation in Zigong City, China. The research employed a mixed-methods approach, integrating quantitative data from 328 student questionnaires with qualitative insights from in-depth interviews to investigate the correlation between satisfaction with literacy plant landscape color and students' physical health, psychological well-being, social relationships, and environmental satisfaction. Statistical investigation utilizing SPSS demonstrated a substantial positive link between the color of literacy plant landscapes and all aspects of quality of life. Linear regression models showed that color psychology, attention restoration, and color harmony are independent predictors of quality of life, notably affecting students' social interactions and environmental perceptions. Qualitative research corroborated these findings, emphasizing the emotional solace and psychological advantages students derive from vibrant, aesthetically pleasing campus green spaces. The findings indicate that augmenting the range and harmony of literacy plant landscape colors can enhance student well-being, facilitate restorative experiences, and cultivate a healthier, more interconnected campus environment. This study provides significant evidence for using color psychology in campus planning to enhance students' physical and emotional well-being.
