Uno's hair is NOT brown I don't think it's even dark enough to be called dirty blond. That said this isn't the first time I've seen characters on the cover have brighter hair than in the actual chapters. Uno's hair has always been a darker shade, it's the same as it was in Red Candy.
The fact that Uno's hair is brown instead of Gold like the manhaw picture better be it's because he purposely dyes it brown !! That's the only explanation I'll except!!
