Do the witchers that get white hair get white hair all over

Do witchers like Geralt and Ciri also get white pubic hair or dose that stay the original color?

I really wonder if that also changes cause if not why not what makes pubic hair special cause irl you could have red or blond hair but black pubes. However may also have blonde pubes with blonde hair.

If the carpet matched the drapes already it will probably change. If it didn't match the drapes dose the magic of the witcher transformation override the black pubic hair color?
