Custom color of ion-icon with google font icon

Ionic Framework Ionic Angular

Hi,

I’m using the ion-icons with custom svgs from Material Font Icons.
Including them with the src property works fine.

Now I want to update the color of those external svg icons. How can I reach that goal?

<ion-icon color="primary"></ion-icon>

This does work for the icons from ionic (ionicons.com) but not for the icons from Google
