I am reading through the docs for UI Fabric React, and I can see that we have these classes to apply font sizes to our labels: https://learn.microsoft.com/en-us/office/dev/add-ins/design/add-in-typography .. I liked the size of the "Subtitle" and "Body" as a header, however the subtitle that is supposed to be a header appears in grey color and the body which is supposed to be the sub label appears to be black. How do we change the default colors when doing something like this:
<Label className="ms-font-l">Hello World</Label>
