Help, I have black hair but there is ginger in my beard?

Yeah, it happens my brother is blonde but his beard is completely red. Also if you use any hair products that contain alcohol or peroxide (or um, bleach, or some acids) it will turn your hair orange, same goes for the skin products, they can get in your hair or beard when you sleep and dye it, (watch out for salicylic acid even) and put some ind of protector in it when you go in the sun- the sun also bleaches hair. However if none of this is relevant, it might just be natural (like it is for my brother!)
