Listen, genetics are pretty weird. I won't go into detail about dominant and recessive genes (here's a link with more info if you really care), but basically, it's not unreasonable that Marinette would have blue eyes even though neither of her parents have them. It's the same principle as two brunette parents having a blonde child (which I can testify to, since that's me and my parents). As long as you have a certain gene in your body, it will always be possible for it to affect your appearance, even if nobody in your immediate family has that same appearance.
