So your hair does not absorb the heat of the sun, and your skin protects itself from burning. Lighter colors reflect more heat, darker colors absorb more. Darker colors are also beter at blocking light, so your skin gets darker to stop the suns rays from penetrating further into your skin

Sun makes the skin darker but does not make hair lighter. Skin naturally responds to sun light by getting more pigment cells called melanocytes. That is a natural defence mechanism of skin. Darker skin can absorb all the sun light and protects humans from sun stroke.

Hi. Hair has chemicals in it which are broken down by ultraviolet light. Skin tries to protect itself by increasing melatonin content, a dark chemical which absorbs sunlight.
