dopamine inhibiting melanocyte stimulating hormone (MSH) which stimulates melanocytes, which produces melanin. Lighter color eyes and skin usually indicates a deficiency in melanin, which is probably caused by dopamine which inhibits serotonin. Meat contains ample amounts of tryptophan, which are mediators for melatonin and melanin which would explain darker pigmentation in eyes and skin in those who eat lots of meat.

As for your eyes, maybe you're balancing out the tryptophan in some way or maybe just genetics. My eyes are pretty dark, so is my hair, but my skin is super pale.
