### `color`

Set the background color. Ignored if a component is specified.

### `component`

Set a react [component](layout-component.mdx) as the background. Useful when you need to show a gradient as background, for instance.


On Android, setting an `id` to the Component will prevent the component from being recreated each time it's used by a screen. The component will be created once and whenever possible it will be reused.
