'Yellow' in the Bible

the priest is to examine the infection, and if it appears to be deeper than the skin and the hair in it is reddish yellow and thin, then the priest is to pronounce the person unclean. It is scall, a disease of the head or the beard.

The priest must then examine the infection on the seventh day, and if the scall has not spread, there is no reddish yellow hair in it, and the scall does not appear to be deeper than the skin,

then the priest is to examine it, and if the scall has spread on the skin the priest is not to search further for reddish yellow hair. The person is unclean.
