Bye Week Dumb Question: Gnash Dash Jersey

Irrelevant to everything, but have yall played that ATT Gnash Dash? Not promoting it, just noticed something curious. Gnash is wearing the navy bottoms with the gold top, but the supposed-to-be-navy sections of the jersey are black. I mean, I know the jersey navy is darker than the pants, but black seems odd.

I'd say this is an oversight, but I'm not entirely sure.Image for the sake of it

EDIT: Bye weeks suck guys.
