If an individual has an rate of blood flow to the skin, such as would happen with emotion (such as embarassment) or alcohol consumption, their skin takes on a tint.

If an individual has an increased rate of blood flow to the skin,such as would happen with emotion or alcohol consumption ,their skin takes on a reddish tinge.

Explanation:

Our skin is provided with a large number of  blood capillaries. These capillaries bring blood and nutrients to the layers of skin. Whenever vasodilation of these capillaries occur, the blood flow to the skin increases and the skin gets a reddish tinge.

During an emotional upsurge such as embarrassment causes the adrenal glands to release adrenaline.

Adrenaline as well as alcohol vasodilates the blood  vessels and increases the flow of blood to the skin. Hence, the skin gets a reddish tinge.
