[![npm package](https://badgen.net/npm/v/@poupe/material-color-utilities)](https://npmjs.com/package/@poupe/material-color-utilities)

Algorithms and utilities that power the Material Design 3 (M3) color system,
including choosing theme colors from images and creating tones of colors; all in
a new color space.

See the main
[README](https://github.com/material-foundation/material-color-utilities#readme)
for more information.

## Getting started

`npm i @poupe/material-color-utilities` or `yarn add @poupe/material-color-utilities`

```typescript
import { Hct } from "@poupe/material-color-utilities";

// Simple demonstration of HCT.
const color = Hct.fromInt(0xff4285f4);
console.log(`Hue: ${color.hue}`);
console.log(`Chrome: ${color.chroma}`);
console.log(`Tone: ${color.tone}`);

```

### Theming

```typescript
import { argbFromHex, themeFromSourceColor, applyTheme } from "@poupe/material-color-utilities";

// Get the theme from a hex color
const theme = themeFromSourceColor(argbFromHex('#f82506'), [
  {
    name: "custom-1",
    value: argbFromHex("#ff0000"),
    blend: true,
  },
]);

// Print out the theme as JSON
console.log(JSON.stringify(theme, null, 2));

// Check if the user has dark mode turned on
const systemDark = window.matchMedia("(prefers-color-scheme: dark)").matches;

// Apply the theme to the body by updating custom properties for material tokens
applyTheme(theme, {target: document.body, dark: systemDark});

```
