What is dry blood color?

Dry blood color can vary depending on how old the blood is. Fresh blood is typically bright red due to the presence of oxygen, while blood that has been sitting for a longer period of time will become darker in color. As blood dries, it can turn a brownish-red color or even black. The color of dry blood can also be influenced by factors such as the amount of moisture, exposure to light, and the surface on which it is located. Overall, the color of dry blood can be an important factor in determining the time frame for when an injury occurred or the cause of a crime scene.
