Terrain or Topography maps

OK, I think that I am down to my last fix. I like having terrain or topography maps for viewers. I created an account with Stamen maps and set my domain. What options should I use in the geolocation plugin to allow me to see terrain on all maps? I guess it is related to the base map or geocoder, but not sure what to select.

It’s actually a theme setting.

that did it thank you.
