9 Blue-Eyed Celebs Who Traded Dirty Blonde Hair For Dark Brunette Locks

A celebrity's look is an important part of their fame. Fans can instantly recognize their favorites on a crowded red carpet. Any deviation from their usual look can become a major talking point on social media. Drastic changes can completely alter a star's appearance, making them unrecognizable — just  take a look at Zooey Deschanel's transformation without her famous bangs as a perfect example. 

When a celebrity changes their hair color, whether it is for a role or just for fun between projects, it can totally change their look. In some cases, like when a blonde darkens their hair, it can bring out an element of their face that was somewhat obscured before, namely their baby blues. Seeing these flaxen-haired stars with dark locks can suddenly make their eyes pop in a way their usual hair color tampers down. Seemingly out of nowhere, their eyes become brighter as they contrast against the deep brown or black of their mane. In some cases, the famous figure may even look better with the change.

While Reese Witherspoon became a household name as a blonde, she is actually a natural brunette. The "Legally Blonde" star was dyeing her hair blonde before she became a household name. Witherspoon shows off her real color from time to time, which can often come as a shock when fans see her.

But there's no doubting that Witherspoon's bright blue eyes really stand out when her hair is darker. Witherspoon is just as glamorous as a brunette, which anyone who has seen "Walk the Line" can attest to, but the change probably makes it easier for her to go to the supermarket without being swarmed by admirers. 

Margot Robbie rose to fame in "The Wolf of Wall Street," where her blonde hair and bright clothes made her stand out from the other characters. She later cemented her place as one of the great blonde actors, playing perhaps the most famous blonde of all time in "Barbie." 

But Robbie has gone with darker shades for some roles, and the change gives her blue eyes a chance to steal the spotlight. The change gives Robbie a whole new look: Blonde or brunette, there is no hiding her beauty and elegance.

Leonardo DiCaprio and his dirty blonde hair made him one of the most crushed on stars when "Titanic" came out in 1997. The actor usually sticks to his more natural hair color, but has dyed it for some roles, including "The Wolf of Wall Street," where he went with a jet-black dye job. 

The dark hair made DiCaprio's icy blue eyes stand out even more than usual. The whole look gave the star a bit of a sinister look, fitting the character he played. It also changed his crush status, scratching away any of the boyish charm he had and adding a touch of danger.

Kate Hudson's naturally curly blonde hair played an important role in her breakout performance as Penny Lane in "Almost Famous," but the actor has gone dark for other roles. In "The Reluctant Fundamentalist," Hudson sported a brunette wig, and the change made her striking blue eyes — a feature she shares with her mom, Goldie Hawn – stand out. 

When Hudson rocks a darker hair color, the green undertones in her baby blues really stand out. The whole look almost makes her look like a different person while also making it almost impossible to keep from having your breath taken away by her beauty. 

Jennifer Aniston's hair became a major talking point when she introduced the world to "the Rachel" on "Friends," a look she has come to regret. Since then, Aniston usually dyes her hair a lighter blonde, hiding away her naturally dark mane and taking away some of the power of her blue eyes. But when she goes brunette, like in "Horrible Bosses," it's impossible not to notice how amazing her eyes are. 

On "The Morning Show," Aniston sports a darker blonde look with highlights of gold. The look not only perfectly frames her face but also makes her eyes stand out, giving co-star Reese Witherspoon a run for her money.

Ryan Gosling's dark blonde hair and blue eyes prove that he is "Kenough" for everyone, but the star has dyed his hair black in the past, giving his peepers a chance to really show what they can do. Not that Gosling needs any help with his looks, but when his locks go dark, it takes his vibrant blues to a new level, instantly drawing you in. 

Looking back, it's hard to believe that he covered up his amazing blue eyes with brown contact lenses for "The Notebook." Who knows how many more tickets the hit movie could have sold if they showed off his natural dreamy irises.

The definition of a California girl, Cameron Diaz has naturally golden blonde locks and piercing blue eyes. The combination instantly made her a star the moment she appeared on screen in "The Mask," but the actor isn't afraid to ditch her iconic look for the right role. 

When Diaz goes dark, her eyes become otherworldly, showing off just how blue they are. The "There's Something About Mary" star is always stunning, but her eyes instantly become the main attraction when her hair is dark. 

With her usually short, wavy blonde hair and blue eyes, Meg Ryan quickly became the world's favorite romantic comedy star. But when the actor wants to show audiences she can be more than a funny romantic lead, Ryan isn't afraid to dye her hair a darker shade.

In 1996's military drama "Courage Under Fire," Ryan sports a brunette bob that changes her entire aura. Her innocent "America's Sweetheart" vibe vanishes, letting the actor show off her dramatic personality while also giving her eyes a dark, piercing quality.

Austin Butler became a movie star when he played the King of Rock and Roll in "Elvis." While the actor had to dye his naturally sandy blonde hair jet black to match the legendary singer's, he didn't need to change his eyes for the role. Just like Elvis, Butler has icy blue eyes that sparkle under the darker locks.

Audiences who saw "Elvis" can attest to Butler's eyes shining through, capturing the same hypnotic gaze as the King. His blue peepers also popped against his white skin in "Dune: Part Two," but the actor went bald for that role.
