Every year on July 12, the world pauses to admire a rare, captivating human feature—different colored eyes, or heterochromia. National Different Colored Eyes Day is a unique celebration of this fascinating genetic trait that sets people apart visually and symbolically. It honors individuality, diversity, and natural beauty while promoting awareness about the condition itself—whether inherited or acquired. This day isn’t just about eye colors; it’s about embracing what makes each of us special. From celebrities to everyday people, heterochromia has long caught the eye of the curious and the appreciative. In 2025, the celebration is louder, prouder, and more inclusive than ever.
📜 History of National Different Colored Eyes Day
National Different Colored Eyes Day was first observed in the early 2000s, though its exact origin isn’t heavily documented. However, the celebration is widely attributed to an American woman named Mary Palan. A passionate advocate for appreciating natural physical diversity, Palan started the day to bring awareness and appreciation for heterochromia—a condition she herself had.
While initially observed among small communities, the observance has since expanded globally. Social media has significantly amplified its reach in the past decade, enabling people with heterochromia to share their stories, post photos, and engage with others across the globe.

Create awareness about different types of heterochromia (complete, sectoral, central).
-
Celebrate physical uniqueness, sending a powerful message that beauty comes in all forms.
-
Boost self-confidence in children and adults with heterochromia who may feel different or isolated.

Ultimately, it’s a reminder that being different is something to be embraced, not hidden.
