 <Spinner text-color="primary" />
 <Spinner text-color="secondary" />
 <Spinner text-color="success" />
 <Spinner text-color="danger" />
 <Spinner text-color="warning" />
 <Spinner text-color="info" />
 <Spinner text-color="light" />
 <Spinner text-color="dark" />

Growing spinner
If you don't fancy a border spinner, switch to the grow spinner. While it doesn't technically spin, it does repeatedly grow!
<template>
 <Spinner spinner="grow" />
</template>

This means they can easily be resized, recolored, and quickly aligned.
