Psicologia das cores
True blue is the world's most popular favorite color, representing trust, competence, and stability. It suppresses appetite and promotes productivity, making it ideal for work environments. Blue is the dominant color in corporate branding because it communicates reliability without emotional excess.
Design Usage
Medium blue is the default choice for primary buttons, navigation bars, and link text across the web. It forms the foundation of design systems for banking, insurance, and enterprise SaaS products. While universally safe, it benefits from a distinctive hue angle or saturation to avoid blending into the sea of blue brands.
