How It Works

Step-by-Step Process

2Choose from complementary, triadic, analogous, monochromatic, or custom palette generation
3Preview your palette with accessibility scores and export in multiple formats (CSS, JSON, Tailwind)

Color Harmony Types

  • Complementary: Colors opposite on the color wheel - creates high contrast and vibrant designs perfect for call-to-action buttons and brand accents
  • Triadic: Three colors evenly spaced on the color wheel - balanced and harmonious, ideal for complex interfaces and illustration work
  • Analogous: Adjacent colors on the color wheel - creates serene and natural palettes perfect for backgrounds and gradients
  • Monochromatic: Different shades and tints of the same color - sophisticated and cohesive, excellent for minimalist designs
  • Split-Complementary: Base color plus two adjacent to its complement - offers high contrast with more visual interest than complementary schemes

Accessibility & WCAG Compliance

  • WCAG AA Compliance: Contrast ratio of 4.5:1 for normal text, 3:1 for large text - meets legal accessibility standards
  • WCAG AAA Compliance: Contrast ratio of 7:1 for normal text, 4.5:1 for large text - exceeds minimum requirements
  • Color Vision Deficiency Safe: Palettes tested for protanopia, deuteranopia, and tritanopia accessibility
  • Real-time Contrast Checker: Instant validation against white and black backgrounds for text readability

Developer-Ready Export Formats

  • CSS Variables: Ready-to-use CSS custom properties for modern stylesheets and design systems
  • JSON Format: Structured data perfect for design tokens, style dictionaries, and configuration files
  • Tailwind CSS Config: Drop-in color configuration for Tailwind CSS projects and utility-first frameworks
  • Sass Variables: SCSS/Sass variable definitions compatible with preprocessing workflows and build systems
