# Chart: Light and dark colors

> A `theme` object picks a different color in each theme. Switch the site theme to see it change.

Example: https://hextaui.com/docs/chart/examples/theme
Component docs: https://hextaui.com/docs/chart.md

## Add this example

```bash
npx shadcn@latest add https://hextaui.com/r/chart-theme.json
```

This adds `components/examples/chart/theme.tsx` with the Chart component and the HextaUI theme tokens.
