 ColorPalette allows the user to pick a color from a list of pre-defined color entries.
 
+## Usage
+
+```jsx
+import { ColorPalette } from '@wordpress/components';
+import { useState } from '@wordpress/element';
+
+const MyColorPalette = () => {
+	const [ color, setColor ] = useState ( '#f00' )
+	const colors = [
+		{ name: 'red', color: '#f00' },
+		{ name: 'white', color: '#fff' },
+		{ name: 'blue', color: '#00f' },
+	];
+
+	return (
+		<ColorPalette
+			colors={ colors }
+			value={ color }
+			onChange={ ( color ) => setColor( color ) }
+		/>
+	);
+} );
+```
+
+If you're using this component outside the editor, you can
+[ensure `Tooltip` positioning](/packages/components/README.md#popovers-and-tooltips)
+for the `ColorPalette`'s color swatches, by rendering your `ColorPalette` with a
+`Popover.Slot` further up the element tree and within a
+`SlotFillProvider` overall.
