Interesting topic! I have reddish blonde hair that gets more blond in summer sun, I have freckles on my upper arms and no where else.
Like someone said, it's all just varying degrees of browness or melanin that makes certain colors when the light reflects off of it. Ever notice how
blonde hair lookd dark brown or black when wet? LOL! It's all how the light plays on it. Same with blue eyes, its how the sunlight reflects off the
melanin in the eyes, just like the sky is not really blue, it just appears that way when it's clear out, same with eyes.
That's why the person
who said her eyes are blue in summer and green in cooler months, just like how the sky is bluer in summer months and grayer in cooler months. There is
no blonde pigment in hair, it's just very little melanin in hair that makes the sunlight reflect off of it to give the appearence of blonde hair. As
we grow older our bodies produce more malanin gradually which is why hair and eyes usually get darker as we grow older. Red hair is different though,
it doesn't work like regular coloring, if you want to wonder about any hair color it's red hair!
Melanin protects us from the deadly rays of the sun and originally the harsher and more sunny the climate, our bodies developed a shield against it
which is melanin. In less harsher climates, the body responded by producing less melanin sort of like muscles you don't use gradually getting
weaker, melanin production became weaker till it was very little melanin produced. In places where the sun rays are so weak, the body makes less
melanin so that some sun rays can be absorbed because we all need some sun rays to live. Once global travel became possible, you can have all kinds of
mixtures appearing anywhere! Even some little african children have blonde hair! LOL! What I really wonder about is albinos!
Now that is just
wierd! I don't know how or where albinoism came from, that's an interesting trait.
