Livor mortis this the color of death. From the word, Livor means color while Mortis means death. After death occurs the body stops pumping the blood. The blood seeps through the tissues and settles down in the lowest part of the body. the settling down of the blood is called lividity and it usually starts after two hours after death.
The red blood cells usually break down and turn color bluish-purple because of the hemoglobin, the hemoglobin usually carries oxygen and gives the blood the red color.  the discoloration becomes permanent after eight hours.

Livor Mortis can reveal information about the time of death in that the color change of the body will happen after two hours. so when you get into a crime scene or near a dead person and when the medic checks the body and can not see the color change it means the death occurred in less than two hours. if the body has changed and when you press some pressure on the body the person died within two hours but if someone exerts pressure on the body and the color still remains the person might have died eight hours or more.
