From what I can learn, Black Herefords are a souped up black baldie. They have to be at least at least 5/8 Hereford and breed true for several generations. They are certainly not a great breed for this area - a little hybrid vigor, I guess, but still dense and hairy, and black. I see they are having a sale in Alvarado in which some lots are advertised as homozygous black. I like red cows myself.
