Color Psychology

Colors evoke emotions - blue conveys trust, red creates urgency, green suggests growth and nature.

Accessibility First

Always ensure sufficient contrast ratios. Aim for WCAG AA compliance (4.5:1) or better.

Color Harmonies

Use complementary colors for contrast, analogous for harmony, and triadic for vibrant balance.

Context Matters

Colors appear different based on surrounding colors. Test your combinations in real contexts.

Brand Consistency

Maintain consistent color usage across your brand. Document your color palette and usage rules.

Cultural Awareness

Colors have different meanings across cultures. Consider your global audience when choosing colors.
