You're hair starts to turn gray as you grow older.
As we age, the pigment cells in our hair follicles produce less melanin, which gives hair its color. As a result, hair appears gray or white. Genetic factors, along with stress and lifestyle factors, can also contribute to the premature graying of hair.
I think gray is associated with age (as in graying hair), and metal.
Gray is the best color to describe it in the truest sense of the color. What I mean is, not gray as in "salt & pepper" colored hair as you age - simply a full healthy gray color which is not found in nature. (rarely if ever). =) Holland's a great character

Some have gray hairs as young as the age of 12, so for people, there hasn't been a set age on getting them.
