Eye color has always sparked conversations, but scientists believe it also reveals personality traits. Researchers at Örebro University in Sweden found that “eye color is affected by the same genes that form our frontal lobes,” linking it to behavior.

**Dark Brown and Brown Eyes**
People with dark brown eyes are “natural leaders” and often seen as “agreeable,” according to *Current Psychology*. Those with very dark eyes drink less alcohol, says *Personality and Individual Differences*. Brown-eyed individuals are “loyal, trustworthy, respectful, and gentle,” but tend to sleep less and struggle waking up (*Chronobiology International*).

**Blue Eyes**
Blue-eyed people are strong inside and out, though others may see them as “shy, untrustworthy, or weaker.” A 2006 study in *The Daily Mail* found blue-eyed children were “wary of new things” and less open-minded.

**Grey Eyes**
Rare and unique, dark grey-eyed individuals are either “well-balanced or two-sided.” Light grey-eyed people work hard to achieve their goals and are guarded, but deeply care once they open up.

**Hazel and Green Eyes**
Hazel eyes are hard to define and linked to a “balanced personality” without extremes (*The Eye Doctor Guide*). Green-eyed people are “original, creative and perform well under great pressure,” with an “air of mystery and a quiet self-sufficiency,” according to Dr. Hamadi Kallel.
