About This Tool
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.
How to Use
- Provide inputs: enter two colors in hex, rgb, or hsl formats and an optional third color for triadic schemes.
- Choose harmony method: complementary, analogous, triadic, tetradic, or auto.
- Run calculation: tool computes harmony score, contrast, and generates alternative swatches.
- Review outputs: inspect suggested palettes and choose preferred combinations; verify text color choices for accessibility.
- Export: copy as JSON, CSS variables, or paste hex codes into design tokens.
