Have you ever wondered what color eyes your baby will have? Will they get mom’s deep brown eyes or dad’s bright blue ones? While we can’t know for sure until the baby is born, a baby eye color predictor can give you a fun and fairly accurate idea of what to expect!
In this article, we’ll explain how eye color is inherited, what a baby eye color predictor does, and how you can try it yourself—no science degree needed!
👁️ What Is a Baby Eye Color Predictor?
A baby eye color predictor is a tool that estimates your baby’s future eye color based on the eye color of the parents, and sometimes grandparents. These tools use simple genetics to calculate the odds of different eye colors (like brown, blue, green, or hazel) showing up in your child.
It’s like a fun science-based guess!
🧬 How Does Eye Color Inheritance Work?
Eye color is mostly determined by genetics, specifically the genes we inherit from our parents. These genes affect how much melanin (a pigment) is present in the iris—the colored part of the eye.
Here’s a quick breakdown:
Brown eyes have lots of melanin.
Blue eyes have very little melanin.
Green and hazel eyes are somewhere in between.
Two main genes affect eye color: OCA2 and HERC2. But over a dozen other genes can also play small roles, which is why predicting eye color isn’t always 100% certain.
🎯 What Are the Chances? (Eye Color Combinations)
Here’s a quick chart to show typical possibilities based on parents' eye colors:
Parent 1 Parent 2 Baby Eye Color Possibilities
Brown Brown 75% Brown, 18% Green, 7% Blue
Brown Blue 50% Brown, 50% Blue
Brown Green 50% Brown, 37% Green, 13% Blue
Blue Blue 99% Blue, 1% Other
Green Green 75% Green, 25% Blue
Blue Green 50% Blue, 50% Green
Note: These are estimates, not guarantees!
🧪 How Does a Baby Eye Color Predictor Tool Work?
Most online baby eye color calculators ask for:
The eye color of both parents
Optional: Eye color of grandparents (for more accurate results)
The tool then uses genetic probability to give you percentages, like:
65% chance of brown eyes
25% chance of green eyes
10% chance of blue eyes
It’s that easy!
👶 Do Babies' Eyes Change Color After Birth?
Yes, they often do! Many babies are born with blue or gray eyes because their bodies haven’t produced much melanin yet. Over the first 6 to 12 months, their eye color may change and darken.
Most eye colors are set by around age 1, but some changes can happen up to age 3.
🟤 Why Is Brown Eye Color So Common?
Brown eyes are the most common worldwide. That’s because the brown-eye gene is dominant, meaning it “wins” over blue or green genes when inherited.
So even if one parent has blue eyes, a baby may still get brown eyes if the other parent carries the brown-eye gene.

🤔 Can I Use Genetics Tests for Accurate Predictions?
Yes—DNA tests can look deeper into your and your partner's genetics to better predict eye color. However, for most people, a simple online tool is good enough for a fun, science-based guess!
🧠 Fun Facts About Eye Color
Blue eyes have no blue pigment—they look blue because light scatters in the iris.
Green eyes are the rarest in the world.
Some people have heterochromia, where each eye is a different color!
📝 Final Thoughts
While a baby eye color predictor can’t guarantee the exact eye color of your little one, it’s a fun and educational way to explore how genetics work. Remember, no matter what color eyes your baby has—blue, brown, green, or hazel—they’ll be perfect.
So go ahead, try a baby eye color calculator and enjoy the guessing game while you wait to meet your baby!
