Adding CSS Class to loader

I'm interested to know how to add multiple progress loaders on a component with different stroke colors. I'm running into issues adding my own stroke color to each of them.

I'm looking to do something like this

```
.vue-progress-path .progress-one {
stroke: red;
}
.vue-progress-path .progress-two {
stroke: blue;
}
.vue-progress-path .progress-three {
stroke: green;
}
```
