Color associations
Blue: Trust, professionalism, calm. Use for finance, security, tech.
Green: Growth, success, health. Use for positive actions, progress, eco themes.
Red: Urgency, danger, passion. Use for warnings, limited offers, CTAs.
Yellow: Optimism, attention. Use sparingly—high saturation fatigues eyes.
Cultural differences
Color meanings shift across cultures. Red = luck in China, mourning in some Western contexts. Always research your audience.
Design globally: rely on context and labels, not color alone.
Strategic CTA colors
CTAs should contrast sharply with the page. If your site is cool-toned, use warm. Orange CTA on blue background beats blue on blue.
Test conversion rates with different CTA colors. Psychology is one factor; design is another.
Emotional response and saturation
Saturated colors feel energetic and young. Desaturated colors feel elegant and mature.
Match saturation to brand personality: startup? Use bright, saturated. Luxury brand? Use muted, refined.
