There are AT LEAST 16 different genes that contribute to the colour of your eyes. Scientists think there might be more.
Producing melanin (like in your skin) gets you brown over blue. But the consistency of the goopy stuff changes the way light refracts and can give green instead of blue. Plus all the others genes having some input too.
So yeah, brown beats blue is not gonna cut it. Two blue eyed parents can have a brown eyed child. And not all brown/blue eyes are the same either.
