What this developer tool does

Uses HSL transformations to build predictable hue, tint, shade, and monochromatic color families.

Parse base color → convert RGB to HSL → apply harmony offsets → convert to HEX → export CSS or JSON.

Generated colors are deterministic for the selected base color and settings.

Example

Base #8b5cf6, analogous palette, five colors, CSS variables.

Tips for better output

  • Run text/background pairs through Contrast Checker.
  • Use monochromatic palettes for restrained interfaces.
  • Keep semantic names when integrating the output into a design system.
