The skin color of the corpse is also an important indicator for determining the time of death.
Generally speaking, a corpse will maintain its original color unchanged for a short period after death.
However, as time passes, the color of the corpse will gradually change.
In non-frozen conditions, the typical color changes of a corpse over time include blue-purple, light red, brown-yellow, wax yellow, light green, dark green, and even black-green.
Without external intervention, the body will eventually become mummified and then undergo decay, eventually leading to skeletonization.
However, under frozen conditions, the color change process of the corpse is different, with the blue-purple process being slower, and if the temperature is low enough, no subsequent decay changes will occur.
Additionally, in some special circumstances, such as death from gas poisoning, the skin color, especially the lips, may exhibit a cherry red hue.
