Newborn Eye Colour: How It Develops and What to Expect

One of the questions I hear most often during newborn sessions — right up there with "will they sleep?" — is: "Do you think those eyes will stay blue?"

And the honest answer is: maybe. But also: it doesn't matter half as much as how extraordinary they look right now.

Here's what actually happens with newborn eye colour, and why it makes those early photos so worth having.

Why Most Newborns Have Blue or Grey Eyes

The colour of your baby's eyes is determined by melanin — the same pigment that determines hair and skin colour. At birth, most babies haven't yet produced the full amount of melanin their eyes will eventually contain.

Melanocytes (the cells that produce melanin) are present at birth but haven't fully activated. The result? Most newborns, regardless of their genetic background, are born with eyes that appear blue, grey, or dark navy — because without much melanin, eyes scatter light and reflect blue tones back to the observer.

Babies with darker genetic heritage may be born with dark brown or hazel eyes that have already developed significant melanin. But even then, there's often a richness and depth to newborn eyes that changes as they age.

When Do Eyes Change to Their Permanent Colour?

The process typically unfolds between 3 and 6 months, though it can continue up to 12 months and occasionally beyond.

After about 6 months, the eye colour you're seeing is likely close to its permanent shade. But there can be subtle shifts — blues deepening to greens or hazels, grey transitioning to blue, brown becoming richer.

The important caveat: genetics isn't a simple prediction. Two brown-eyed parents can produce a blue-eyed child. Two blue-eyed parents will always produce blue-eyed children. Eye colour inheritance involves multiple genes, not just dominant/recessive pairs.

What This Means for Photography

The newborn eye — whatever colour it is right now — is photographically extraordinary. Those wide, dark pupils, the translucency of the iris, the way studio light catches them at just the right angle. Close-up eye shots are consistently among the most-requested and most-loved images in any newborn gallery.

When I photograph a baby's eyes, I'm not trying to predict what colour they'll be in six months. I'm documenting exactly what they look like on Day 7 — a version of those eyes that doesn't exist again.

FAQ

My baby was born with dark eyes — will they lighten?
Probably not significantly. Babies born with dark brown eyes typically have enough melanin already present that their eyes won't change dramatically. Light eyes in dark-eyed newborns is much rarer.

Is there any way to predict eye colour?
Loose predictions based on both parents' eye colours are possible. Eye colour calculators online can give probabilities. But genetics at this level is genuinely complex — surprises happen.

Do premature babies develop eye colour differently?
Generally no — the melanin development process follows a similar timeline based on gestational development rather than birth date.
