Here's best answer I found on quora for eye color, which I copy and paste below: http://www.quora.com/Does-the-color-of-ones-eye-serve-a-purpose-in-the-ability-to-see-Is-it-evolutionarily- advantageous-to-have-green-or-blue-eyes -Moshe Brown eyes protect the retina from harmful uv-light, much the same as dark skin protects you from skin cancer in sunny climes. However, this comes at a price, the melanin blocks some visible spectrum light from entering the eye too; particularly light towards the blue end of the spectrum. This means it is harder to see at night, as it means you cannot see the predominant wavelengths of the visible spectrum that are still shining, at say twilight. In areas where in winter it may be night for 12 hours a day or longer, good night vision is crucial, and uv protection less so - hence scandinavia is famous for blue eyes. Blue eyes are eyes with a relative absence of pigmentation; green I imagine is just a happy medium between blue and brown, offering some of the advantages of both. A complete absence of pigment in the eye causes red eyes (as you can see all the blood vessels). This is seen in albinos. As an interesting aside, ninjas actually wore blue at night, not black, to exploit the fact this is the predominant colour that one can see at that time, and so they blend in better than if they had worn black as is commonly portrayed.
