Those with pale skin naturally produce more vitamin D. This is because the pigmentation in your skin (Melanin), which protects skin from sun damage, also reduces vitamin D production. Pale skin is in fact an evolutionary adaptation to living in less sunny climates. That's why Vitamin D deficiency, in an un-sunny climate like Britain, is more prevalent in British Asian and Black British populations than in White British. This "redheads" association is due to red hair often being associated with pale skin, and not specifically due to hair colour. Some of the genes associated with less skin pigmentation also result less hair pigmentation (blonde or red hair).
