Question about red hairs in beard

[blurp]

Hello, I am someone who is adopted and I have no idea where I'm from because it's being kept a secret from me on purpose. I am a person who seems to be racially mixed, I have jet black, wavy hair and I don't have much facial hair. However in my beard I seem to have quite a few orange hairs, most of them are black however some of them are orange or red. Is this an indication of me being a recessive red hair carrier, or could it be the result of a mineral deficiency? Let's just say where I live there are no commercial genetic testing sites available that are that analytical, and the results could be skewed.
