 ## Background colors
 
-Use our background utility classes to quickly change the appearance of a badge. Please note that when using Bootstrap's default `.bg-light`, you'll likely need a text color utility like `.text-dark` for proper styling. This is because background utilities do not set anything but `background-color`.

 ### Color schemes
 
-Building on the above example, you can create different toast color schemes with our [color]({{< docsref "/utilities/colors" >}}) and [background]({{< docsref "/utilities/background" >}}) utilities. Here we've added `.bg-primary` and `.text-white` to the `.toast`, and then added `.btn-close-white` to our close button. For a crisp edge, we remove the default border with `.border-0`.
