Because you have a infection or dirt in it
A scab can turn green due to the presence of certain bacteria, particularly those that produce a green pigment, such as Pseudomonas aeruginosa. This pigment, called pyocyanin, can indicate an infection and may alter the color of the scab as the healing process progresses. Additionally, the green color may also result from the breakdown of hemoglobin in red blood cells, leading to changes in pigmentation. If there's concern about an infection, it's important to consult a healthcare professional.
