Reference & details

How it works

Color Space Conversion

The Color Mixer converts between RGB, HSL, HSV, and hex using standard linear transforms. Gamma-correct sRGB values are assumed unless otherwise noted.

HSL ↔ RGB via standard cylindrical transform

Accessibility Checks

Contrast ratios are computed per WCAG 2.1 relative luminance formula. Results indicate AA and AAA compliance for normal and large text.

Contrast = (L1 + 0.05) / (L2 + 0.05)

Output Formatting

Generated values are emitted in copy-ready formats (hex, CSS, Tailwind, SVG). Precision is tuned for design tools without unnecessary floating-point noise.
