Tâm lý màu sắc

True green represents growth, harmony, and environmental consciousness. It is the color most directly associated with nature and sustainability, activating feelings of renewal and stability. Green sits at the center of the visible spectrum, making it psychologically balanced and universally positive.

Design Usage

Medium green is essential for sustainability brands, financial growth indicators, and agricultural products. It works as a primary brand color that communicates trust without the corporate coolness of blue. Ensure sufficient contrast with white text since many mid-greens fall below WCAG AA thresholds.
