In color psychology, green often represents nature, wealth, and health. The color evokes feelings of growth, fertility, relaxation, harmony, and generosity, though it can also carry negative connotations such as envy. The shade of green influences its psychological impact: lighter shades indicate calmness and peacefulness, while dark greens are associated with prestige and wealth. In branding, companies like John Deere use green to emphasize their connection to the natural environment.
