all things will happen due to the secretions of the hormones and combinations of chromosomes so humans have different eye colours; true, however it also depends on how much melanin your eye contains. If you are very pale, you will notice that your eye color can change, because it can reflect your clothing colors. Someone with lots of melanin (i.e. dark skin) will have dark brown eyes. the more melanin you have in your body, the darker your eye color.

I think that the difference between human eyes & dog eyes is that all dogs are color blind but not all humans are color blind. We can see in color as dogs cannot.Yes this is the maindifference but I would like two point out that through dogs are color blind that they do indeedsee in color but they are missing a type of cone that humans have and they have way less.
