Color Match Tool

This tool analyzes two input colors and reports how well they work together under commonly used harmony rules. It accepts hex, rgb, or hsl formats, normalizes to a standard space, and returns an immediate ranking of compatibility.

Conceptually, it relies on color science principles: color distance in a perceptual color space, harmony rules, and luminance calculations for accessibility. It suggests harmonies (complementary, analogous, triadic, tetradic) and can generate alternative swatches to broaden the palette.

Who benefits: brand teams, product designers, developers implementing design systems, and accessibility engineers. Use cases include creating landing page palettes, theming tokens in CSS/JSON, and validating contrast ratios against WCAG thresholds.

Unique value: automated harmony scoring, ready-to-export palette formats, and guidance on text color choices for readability. Core features include input normalization, multiple harmony strategies, contrast checks, palette exploration, and export options. It saves time and supports consistent visuals across products.
