It isn't correlated with hair and eye color. That is my experience in life. The colorations in my immediate family run the gamet from black hair and
black eyes, to brown hair and brown eyes, to grey eyes and red hair, to blonde hair and blue eyes. We are all somewhat psychic.
If anything, the psychic ability is in most people, and in some families, it is more prominent than others. Perhaps in some families, it is an
acceptable thing to talk about and be comfortable with, and in others, it is not acceptable and is thought of as new-agey and kooky. Of course,
certain colorations run in certain families (unless you are a Heinz 57 mix like my brothers and myself).
In my family, the only one of us who isn't really psychic is my blonde-haired, blue eyed brother. He has had a few pre-cognitive dreams, but mostly
he spends time in jail for parole violations. Like he couldn't see that coming!
