You can go to http://museum.thetech.org/ugenetics/eyeCalc/eyecalculator.html and see the probabilities for what color eyes you and your SO's children will have.
I may or may not have put a spouse with blue eyes. Which may or may not been for Hugh and Haldir. Which may or may not have shown that it would be impossible for us to have brown-eyed children. They would all have either blue or green eyes.
Interestingly enough, it calculated my parents as have 25% green, 25% blue and 50% brown-eyed children. I have green eyes, two of my sisters have brown eyes, and the third one has blue eyes. Scary, no?
