'Reddish' in the Bible

The first son came out reddish his entire body was covered with hair so they named him Esau.

But when in the baldness of his head or his forehead there develops a skin rash that's white or reddish, it's an infectious skin disease that has spread to his bald head or forehead.

When the priest examines it and finds that the swelling of the skin rash is white or reddish on his bald head or forehead, similar in appearance to an infectious disease in the skin of the body,

if the contagion is greenish or reddish in the clothing, leather, woven material, knitted material, or with any article containing leather, it's a fungal infection and is to be shown to the priest.

He is to determine if the contagion is indeed on the walls of the house, with greenish or reddish streaks, and to determine if it appears to be deeper than the surface of the wall.
