The change of hair and eye color from kid to adult is normal... I don't know a single person who doesn't have a story like yours.
My eyes were brown when I was born and now they are greyish blue, my hair was light brown / very dark blond) and now it's dark brown. No real mystery
there I think.
Why your eyes would change color when you are angry I don't understand though. When you get mad you tend to have lots of blood pumped into your head,
so that change in skin coloration caused by this amount of blood could, when view against your eyes seem as if your eyes changed colors.
When I get really mad myself or choke on something really bad my eyes seem lighter in coloration than normally.
Soon my eyes will turn green.... but that's just because I bought contacts

color change problem solved, hehe
