'Appearance' in the Bible

The priest is to examine it, and if the swelling of the infection is reddish white in the back or front bald area like the appearance of a disease on the skin of the body,

The priest must then examine it after the infection has been washed out, and if the infection has not changed its appearance even though the infection has not spread, it is unclean. You must burn it up in the fire. It is a fungus, whether on the back side or front side of the article.
