Will I get their eye color?

if both of my parents have light eyes,amber and hazel,is there a chance I can get light eyes 2 and if yes like what color???

The gene thingy also accounts for you possibly getting brown eyes. My own eyes were browner when I was young and changed to an amber/hazel with age. They change at times to be more green or more amber. Brown eyes are a dominant gene and will remain in the bloodline regardless and if there was any brown eyes in the family of either parents there is still a chance for brown-eyed babies.

Shouldn't you know your eye color already...?

Not unless you were born with them. Dark eyes are nice anyway, embrace it!
