My eyes change color too, though I can't do it on command like Pescado can. They range between reddish-brown to muddy green-brown.

My understanding is that to have blue, green, grey or hazel eyes, you need to have the (recessive) gene on both sides of the family, in other words, both parents have to be carrying it, but it may have never actually appeared for generations, and can make it's appearance simply because it finds a match.
In my family, my mother had brown eyes, my father had blue, and we all got blue or blue/grey. However, my sister's daughter has brown eyes like her father.
Also, if both sides of the family have only the blue-eyes gene, then brown eyes are an impossiblity, so if Afro-American, or Afro-British etc. parents both have blue eyes, then their children will as well. You need two blue-eyed genes to have blue eyes, only one brown-eyed gene for brown.
I may have this a little confused, so any biologists out there who can correct me, I stand corected.

Unfortunately it isn't that simple and hair and eye colour do not follow the straightforward Mendelian inheritance patterns you are taught in school. Both eye colour and hair colour are determined from 8 different alleles each expressing different amounts of melanin. It's unlikely having both parents with blue eyes would produce brown eyed children however it can happen.

I felt I'd probably got some of it wrong (or over-simplified). And bear in mind, it's a long time since I went to school!
Ancient Sim:
It's amazing what weird things can happen with genetics. I remember years ago, a white couple who lived near my fiance at the time had a dark-skinned baby. They were both extremely puzzled (the husband may have been a little more than puzzled!), so much so that they had genetic tests done and investigated both family trees. Turned-out that someone way back in (I think) the wife's family had married a Jamacan or something. I don't recall their names, but they were probably called Jill & Pollination Tech#9 Smith, or something very similar.
