What term is used for the mildest form of frostbite?

Laudy Miss Claudy, Great question, the colors intensify on dark skinned people, and whiteness or lightness will occur.

"...skin becomes reddened, pale, and white in the first stage of frostbite". So how do you identify frostbite if the person's skin is brown?

I’ve only knew one person that got frostbite and that’s my cousin. He died a while back but yeah he got frost bite bad.

Laudy Miss Claudy, yes, how??
