   Stanford GSB Chile Chapter
   Light, editorial, photography-forward — anchored to Stanford's real brand
   (Cardinal red, Source Serif headlines, Source Sans body, generous white
   space) with a Chilean accent system drawn from the country's materials:
   copper and warm sandstone, the way Stanford draws its own secondary palette
   from "campus architecture and the California landscape."
