Color Harmony

Colors that look good together are called color harmonies. Common harmonies include complementary, analogous, and triadic color schemes.

Accessibility Matters

WCAG recommends a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Aim for AAA (7:1) for optimal accessibility.
