I agree with you. However, Alec Jeffreys (of DNA fingerprinting in humans 
fame) came to the Cambridge Science Park in 1993 to give a talk. He 
started by looking at the audience and saying something like "I suppose 
most of you will be surprised if I told you that 10% of the audience do 
not have the father that they think they have..." ;-)

No, seriously. I don't think you can question paternity simply looking at 
the eye colour.
