Pallor mortis (Latin: paleness of death) is a postmortem paleness which happens in those with light skin almost instantly (in the 15–120 minutes after the death) because of a lack of capillary circulation throughout the body. The blood sinks down into the lower parts of the body creating the Livor mortis.

Paleness develops so rapidly after death that it has little to no use in determining the time of death, aside from saying that it either happened less than 30 minutes ago or more, which could help if the body was found very quickly after death.
