What is the color of a pressure sore?

Pressure sores, or 'bed sores,' may be red, pink, yellowish or dark in color. Bedsores are classified into one of four stages, based on severity, according to Mayo Clinic.

Stage I sores often appear pink or red in color on light-skinned individuals or discolored on darker skin, cites Mayo Clinic. Stage II bedsores contain a shallow pink or red wound and may appear as a fluid-filled blister. Stage III sores may contain yellowish dead tissue at the bottom of a deep crater-like wound.

Stage IV pressure sores are marked by a large-scale loss of tissue; yellowish or dark and crusty dead tissue is typically present at the bottom of the wound.
