Color Palette Generator
Generate complementary, analogous, triadic and split-complementary color palettes from any base color.
About the Color Palette Generator
A color palette generator creates harmonious, aesthetically balanced color schemes for website design, brand identities, interior decorating, and digital illustrations based on classical color theory principles.
The tool generates palettes using established harmonic models: Complementary (colors opposite on the color wheel for dynamic contrast), Analogous (adjacent colors for soothing unity), Triadic (three evenly spaced colors for vibrant balance), and Monochromatic (varying shades, tints, and tones of a single hue).
Each generated palette provides HEX, RGB, and HSL codes, alongside accessibility contrast scoring to verify that text colors paired against background hues meet WCAG AA legibility standards.
A primary royal blue (#2563EB) paired with an analogous slate accent (#3B82F6), a soft surface background (#F8FAFC), a deep charcoal typography tone (#0F172A), and a complementary amber call-to-action (#F59E0B).
Tips for best results
- Follow the 60-30-10 interior and UI design rule: 60% dominant neutral background, 30% secondary structure color, and 10% high-contrast accent color for buttons and focal points.
- Limit your core brand palette to three to five colors to maintain visual cohesion across marketing materials.
- Verify color contrast against WCAG AA standards (minimum 4.5:1 ratio for body text) using the built-in accessibility indicator.
