About This Tool

The tool accepts a base color and applies color theory to generate coherent palettes. It supports harmony types such as analogous, complementary, triadic, tetradic, and monochromatic schemes, producing a set of hex codes that can be used directly in design assets. It analyzes contrast against chosen text colors and offers optional adjustments to saturation and lightness to balance vividness with readability. Outputs include hex codes, CSS variable formats, and JSON exports for rapid integration into development workflows. Advanced users can enable accessibility checks and automatically balance luminance to meet WCAG recommendations. The system is designed for designers, front-end developers, and marketing teams who need repeatable color systems across multiple components or pages. Its unique value lies in accessibility-aware options, fast exports, and a solid foundation in color theory that reduces trial-and-error during palette creation.

How to Use

  1. Provide inputs: select base color, choose harmony type, and set palette size.
  2. Optionally adjust saturation and lightness ranges for desired vibrancy.
  3. Run calculation to generate the palette.
  4. Review outputs: hex codes, CSS variables, and any accessibility notes.
  5. Copy or export results to integrate into design or code assets.
