That one isn't the article I thought it was from the google results, but there are several articles listed as related stories that may apply.
That one's interesting, though. The blue-eyed co-vivant and I met on line and I guess he neglected to ask what colour my eyes were.
He got my brown eyes, I got his diabetes and aversion to employment ... (I should be fair; he had previously had high-powered sales job in the office equipment industry, with Xerox and the like; the "inside sales" part of the industry collapsed around the time we met, with the internet and big box stores, and order clerks took the place of people like him. And middle age is not an advantage for job hunting as a sales "professional"; my dad suffered the same fate.)
ScienceDaily (Oct. 23, 2006) Before you request a paternity test, spend a few minutes looking at your childs eye color. It may just give you the answer youre looking for. According to Bruno Laeng and colleagues, from the University of Tromso, Norway, the human eye color reflects a simple, predictable and reliable genetic pattern of inheritance. Their studies1, published in the Springer journal Behavioral Ecology and Sociobiology, show that blue-eyed men find blue-eyed women more attractive than brown-eyed women. According to the researchers, it is because there could be an unconscious male adaptation for the detection of paternity, based on eye color.
-- except that the some of the "science" it goes on to spout -- that two blue-eyed parents can't have a brown-eyed child -- is crap. It does say, though (and I still think the part about 1/4 of children is crap; maybe a 1 in 4 chance for each child, which in our case made 4 kids out of 4):
If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes.
There are so many people spouting incorrect information about this on the net it's hard to find the facts. This is not your grandmother's genetics anymore, people!
Here we are, finally -- give your son this one.

Example 4
Parent 1: Brown Eyes, Genotype: bey2: Brown-blue, gey:Green-blue
Parent 2: Brown Eyes, Genotype: bey2: Brown-blue, gey:Green-blue
(and then there's a diagram)
Each child has a 75% probablility of brown eyes and a 18.75% probability of green eyes and a 6.25% probablity of blue eyes. On average, about three quarters of the children of this cross will have brown eyes, three sixteenths green eyes, and one sixteenth blue eyes.
Nothing there about blue- and green-eyed parents producing all brown-eyed kids, though.
But I can produce us at the eye colour calculator, and now I remember doing that some time ago:

So women, if your kid has odd eyes, send all the aunties and in-laws whispering behind their hands there!
