# Color Palette & Contrast Checker

Version: 0.1.0
License: MIT

Create complementary, analogous, or triadic palettes from a HEX color and view black/white WCAG relative-luminance contrast ratios.

## Run
Open `index.html` in a modern browser. No install or server required.

## Limits
Ratios use opaque sRGB values. They are a planning aid; verify actual text/background pairs and do not use color alone to communicate meaning.

## Environment
Modern browser with JavaScript enabled. All calculations run locally.
