Blonde as kids, brown as adults have dominant brown gene. It is possible to have a double recessive blonde hair child, but (80% against) unlikely if both parents carry the brown gene. Genetics!
This is oversimplified and kind of incorrect. Eyes are either pigmented (brown) or unpigmented (everything else). There are several genes that determine the exact shade of unpigmented eye. Two blue-eyed parents can have children with hazel/green/grey eyes. The genes that determine eye color are also very susceptible to mutation. Unpigmented eyes were likely a mutation somewhere in human ancestry, or else we would all have brown eyes.
For the record, I have unpigmented eyes and they have changed color over the years from caramel-brown to amber-green. My DC's eyes are blue-grey.

Red hair, like blonde, is recessive. Somewhere in both of your parents' families, there was red hair.
My parents both had red hair and of their seven children, only one (I) had red hair. I married a redhead and we have three redheads - but we could as easily have had none.
Somewhere. None of my aunts, uncles, cousins, grandparents have red hair.
Maybe PP was right about the mailman.

So, if I have blue eyes and my DH has green eyes, can our child have brown eyes?
