I doubt that you'll actually know what color your child's eyes and hair will be until they're older, say in grade school and even then you can't be sure they'll stay that color. It's been my experience that our eye and hair colors can change thru out our lives but also they don't necessarily change. Two of my brothers still have blue eyes very similar to the blue that they were born with. Neither on has much hair now. smile
I started out with very blue eyes which stayed that color for all of my childhood. Sometime in my early 20's they started to take on a greenish tinge and then sometime during the years they added a brown color. I don't have a name for their color now. They're a mixture of colors similar to my mother's. My father had clear blue eyes as did his mother.
Some would say the color of our eyes is influenced by our diet. I don't know if that is true. My eyes could've become this mixture of colors because of genetics. My mother's eyes were always more brown than blue and green. My eyes are still more blue/green but now also have brown in them.
My granddaughter and grandson were both born with definite eye color. My granddaughter's were brown soon after birth and my grandson's were blue. My grandson who is now 7 still has very clear blue eyes. My granddaughter's eyes are getting more green in them as the years go by. She's 10 now. Their mother has always had clear blue eyes and a dark complexion with curly dark hair. My granddaughter's father is black and has definite brown eyes. My grandson's father, who has a Spanish ethnic background, also has a dark complexion and very dark eyes. My grandson is fair skinned with dirty blonde hair and very clear blue eyes. His hair was close to the same color it is now when he was born but it became a light blonde during his early years, sometime during the first few months, and has reverted back to a darker color now.
This is similar to the way my brothers and my hair color changed. We were born dark blonde, had very blonde hair during the toddler years and and then hasdarkened over time into a light brown until it reversed and became gray and then white. lol
This is all to say that everyone is different and even the color of our eyes and hair can change as we mature. At the same time, some people's eye and hair colors stay close to the same. One reason for this is our genetic background. To more accurately predict eye, hair, and skin color, as well as all the other characteristics we have, one has to go back several generations and study the genetics.
Genetics is interesting. I learned about it in science class in high school but I remember very little now. One thing that struck me so strongly that I've remembered it is that a child can be born not looking like either parent. At the time "they" called this a "throw back." I've heard of 2 white parents having a black child and not knowing that there were black genes in their family background were sure the hospital had made a mistake.
If you want to know more about the potential for your child's eye and hair color Google genetics and make a chart of his ancestors. We did that for science class. I enjoyed doing it.
