When a person is overheated why does the skin become flushed and hot?

When the core body temperature rises, the peripheral vasculature dilates, specifically the small arterioles and capillaries under the skin. This is to help lose heat by conduction. You also will sweat, to lose heat by evaporation.

Can people turn black using only with the sun?
No, people cannot change their skin color to black solely by exposure to the sun. Skin color is determined by genetics and the amount of melanin, a pigment found in the skin. The sun can darken a person's existing melanin, resulting in a tan, but it cannot permanently alter a person's genetic makeup or produce a permanent change in skin color.

A person who is overheated will have a red flushed appearance a person who is chilled will be pale with blue finger tips explain this appearances in terms of the body's control of one of the methods?
hot = vasodilation (the veins are dilated) when a person's body temperature is up, the reason they become flushed and have the reddish tint to the skin is b/c the veins are dilated and blood is close to the skin surface. this is the body's way of attempting to cool down. cold = vasoconstriction (the veins are constricted) a person looks pallored (pale) and cyanotic (bluish) when their temp is down b/c the veins are constricted and blood is not close to the skin surface. this is the body's attempt to conserve heat. HOUNDDAWG adds: Presumably most of the answer applies only to light skinned people such as Caucasians. Just as Crayola Crayons used to have one color labeled "flesh" the above answer is a bit insensitive to the fact that most of the people of the world do not have skin the color of that now wisely discontinued crayon, and most do not turn red or blueish with extreme body temperatures. But, anyone who does not is indeed "a person" as used in the above question. Fingernails may still be blue if a darker skinned person is cyanotic or cold, but skin temperature to the touch will also answer the question for responding medical personnel, and shallow or labored breathing, pulse and other vitals will reliably aid in assessing a person's condition if they're not "a person" in some limited context such as the question posed.

Why does a person's skin get red when they're hot?
The body has a core temperature of about 98.6F for most people. If you are in a hot environment, or have just taken a nice hot shower/bath, your core body temp is going to be affected. To get rid of the heat, the superficial blood vessels, just under your skin, dilate to release the heat to the skin, sometimes in the form of perspiration with a little help from the eccrine (sweat) glands. When those blood vessels dilate so close to the surface of the skin, it causes the skin to become red, flushed or florrid.
