Indeed it is an interesting topic. I used to think the thing about the eye colour "jumping a generation" to be bullshit, but I have seen it in so many couples (children of couples both with brown eyes, for example, inheriting blue or green eyes from a grandparent or great-grandparent).
I have brown eyes (so have the last two generations of direct family) and my husband has blue eyes (so has the last three generations in all his family!). I have only one daughter, and as I was pregnant I was so sure she would be born with brown eyes that I told my husband: "If she is born with brown eyes it is the evidence of the power of my blood". Needless to say my daughter has blue eyes!
Another story: as she was a baby, I was all proud of her blue eyes.
So I met this woman casually in a shop, she looks at my daughter and says: "Oh, she has blue eyes". I smiled all happy, but the lady looked disappointed. She says to me then: "You know, I have four children. First one was born, blue eyes; second one was born, blues eyes;third was born, blue eyes. Finally in the forth one I got lucky and she was born with beautiful brown eyes like her father".
I went away smiling, it is all always a matter of perspective.
