Different color hair on body?

Sorry if this isn't the best place to post this question, but I can't find a more suitable subreddit?

Basically I'm wondering if anyone has the same/similar issue(?)?

The hair on my head is dark ginger, beard and moustache light ginger, and "down below" is ginger, but my chest hair is dark brown/black and my arm and leg hair is so light it's almost white?

I don't class it as an issue myself, I'm just asking out of sheer curiosity if anyone else has a similar condition?
