Baby Eye Color Predictor
This is a fun tool using simplified genetics, not a scientific prediction.
Those tiny windows to the soul—will they be blue like the ocean, brown like warm earth, or green like forest leaves? Let's explore the beautiful lottery of genetics.

“Eye color is one of nature's most fascinating genetic dances, mixing melanin, genes, and a touch of beautiful unpredictability.”
The Genetics Behind Eye Color
Eye color isn't as simple as the genetics lessons you might remember from school. While brown eyes are generally dominant and blue recessive, modern genetics has revealed that at least 16 different genes influence eye color, making predictions educated guesses rather than certainties.
The two main genes involved are OCA2 and HERC2. Together, they determine how much melanin is produced in the iris. More melanin creates brown eyes, while less melanin results in blue, green, or hazel eyes. The specific combination and interaction of these genes creates the beautiful variety we see in human eye colors.
Eye Color Facts
- Brown is the most common eye color worldwide (79%)
- Blue eyes are most common in Northern European populations
- Green eyes are the rarest, found in only 2% of people
- Hazel eyes can appear to change color in different lighting
- All babies start with low melanin production
Common Questions
Can two brown-eyed parents have a blue-eyed baby?
Yes, though it's uncommon. If both parents carry recessive blue eye genes, there's approximately a 25% chance their child could inherit two blue genes, resulting in blue eyes. Family history can provide clues about hidden recessive genes.
When does a baby's final eye color develop?
Most babies' eye colors stabilize between 6-18 months, with final colors typically established by age 2-3. Some children experience minor changes throughout childhood. Melanin production increases gradually after birth, causing lighter birth colors to darken over time.
Why do eye colors seem to change in different lighting?
Eye color appearance can vary significantly in different lighting conditions, especially for hazel, green, and gray eyes. This happens because these colors have complex pigment patterns that reflect light differently. The eye color isn't actually changing—different aspects of the existing pigmentation become more visible under various lighting.
