Livor mortis starts within 20–30 minutes, but is usually not observable by the human eye until two hours after death. The size of the patches increases in the next three to six hours. Fixation will begin to occur during this timeframe, causing the patches to be unaltered due to movement. Maximum lividity will occur between eight and twelve hours after death. Areas of blood pooling in contact with the ground will blanch, or remain white. The blood pools into the interstitial tissues of the body. The intensity of the color depends upon the amount of reduced haemoglobin in the blood. The discoloration does not occur in the areas of the body that are in contact with the ground or another object, in which capillaries are compressed.
