      Blushing is a physical condition caused by over-activity in the so-called sympathetic nervous system, a system made up of nerves over which we have no control. These uncontrollable nerves may become especially active due to social and emotional stimuli and may be very embarrassing.

      Turning pale on the other hand is the response of the parasympthetic
      nervous system. It responds just oppositely of the sympathetic system.

      the direct effect occurs because of widening or tightning of blood vessels beneath the skin

      aka ateriole dilation (for blushing) or constriction (for going pale).
