With the exception of a brief stint as a full-blown brunette in 2014 — she was nearly unrecognizable at the Oscars that year with her super dark surprise shade — Margot Robbie is almost exclusively a blonde. You picture her, you picture blonde hair. I don't make the rules. But the 2021 Oscars have given Robbie a new opportunity to debut darker hair. And while it's not nearly as dark as seven years ago, it's definitely a departure for the actor.
