Animal colour
Animals can have a camouflage defence at distance, but when faced by a predator they may switch to a 'flash' defence to gain time and distract the predator. The predator often blinks or turns its face away in self-defence. This is a reflex act which is there to protect its vital facial area. In the second the predator blinks, the prey flies or jumps, and lands in camouflage again. This pattern of color plus behaviour is quite common. It is called deimatic defence by textbooks, from the Greek for 'dread' or 'to frighten'.
