Are blue or green eyes prettier and explain why

That depends on a person's preference, seeing as that would be a person's opinion. I personally like blue eyes over green ones, why? I just like the color blue.

I would have to say green eyes. Green eyes could be your favorite color or you just love people with green eyes. I have blue eyes, but I prefer green eyes. They could be colors of the spring bright green leafs. They can maybe change color in the sun.
