Chances are you'll get some sort of a red baldie - it might be Hereford marked, it might not. There's also a chance (statistically I'm thinking 25%) that the calf could be black, prob'ly a baldie. Could possibly even be solid black or red, or at the other extreme even a paint - neither are likely, but it does happen. Like hntwhitetail says, there's a good chance it'll be colored similiar to it's mother, but you just have to remember there are lots of different possibilities.
