Even when Rachel McAdams isn’t frequenting red carpets, she lives rent-free in most of our brains as a beloved actor and timeless beauty icon; she moved in about 20 years ago and just never left. And I think I speak for most of us when I say the default mental photograph of McAdams is a blonde one. But as of this week, she’s sporting a hair color we rarely see on her — and a pattern may be emerging.

For the last few years, McAdams has been seen wearing gorgeous variations of bronde — an overall blonde shade with a fair amount of brown mixed in (see above). But when she arrived at the opening night of Broadway’s An Enemy of the People, it became clear that she’s got much more than just a fair amount of brown mixed in. She’s now a full-blown brunette.

The new hue is a rich medium brown with hints of caramel highlights. She wore her hair deeply side parted with smooth, shiny, loose curls cascading over her navy blue turtleneck.
