<div class="doc-content">
<h2>Using CSS Variables</h2>
<p>The simplest way to use hue.gl is with CSS variables:</p>
<pre><code>/* Import the stylesheet */
@import 'hue.gl/dist/css/hue.gl.css';
/* Use any color */
.button {
background: var(--N2405); /* Blue, shade 5 */
color: var(--N0601); /* Yellow, shade 1 (light) */
}
.card {
border: 1px solid var(--N1803); /* Cyan, shade 3 */
}</code></pre>
<h2>Using SCSS</h2>
<p>Import SCSS variables and maps for more control:</p>
<pre><code>@use 'hue.gl/dist/scss/hue.gl' as hue;
.element {
// Use color variables
background: hue.$n240-5;
// Use the color map
color: map-get(hue.$colors, 'N0601');
}</code></pre>
<h2>Using JavaScript</h2>
<p>Import colors programmatically:</p>
<pre><code>import { ColorScheme, getColor } from 'hue.gl';
// Get a specific color
const blue = getColor('N2405');
console.log(blue.hex); // #3b82f6
console.log(blue.rgb); // [59, 130, 246]
console.log(blue.lch); // [55, 70, 240]
// Create a color scheme instance
const scheme = new ColorScheme();
const palette = scheme.getHue('blue');</code></pre>
<h2>Color Naming Convention</h2>
<p>Every color follows this pattern:</p>
<table class="doc-table">
<thead>
<tr>
<th>Part</th>
<th>Description</th>
<th>Example</th>
</tr>
</thead>
<tbody>
<tr>
<td><code>N</code></td>
<td>Prefix (NIJI system)</td>
<td>N</td>
</tr>
<tr>
<td><code>240</code></td>
<td>Hue degree (015-360)</td>
<td>240 (blue)</td>
</tr>
<tr>
<td><code>5</code></td>
<td>Shade number (1-9)</td>
<td>5 (middle shade)</td>
</tr>
</tbody>
</table>
