What color indicates a healthy regeneration of tissue in an open wound?

The color red signifies a healthy regeneration of tissue in an open wound, indicating that the healing process is progressing well. This vibrant red hue generally reflects the presence of new, healthy blood vessels in granulation tissue, which is characteristic of the proliferative phase of wound healing. At this stage, the body is actively supplying nutrients and oxygen to the area, promoting tissue repair and regeneration.

In contrast, other colors like black typically indicate necrotic tissue, which is unhealthy and may require debridement. Yellow can suggest the presence of slough or infection, while blue often signals poor circulation or oxygenation, which are both concerning for wound healing. Therefore, red is the color associated with a positive healing response in open wounds.
