This reply is a little late.
A friend of mine had what is believed to be the only privately owned herd of African Forrest Buffalo outside of their homeland... Sadly these animals died in a fire on his reserve. I believe they did have a red tinge too them... Will check up with him and get some more info on their colouring from birth to adult and whether it was the hair or skin pigmented... They appear to be smaller in frame, with smaller cape and horns [ears appear larger to me, I could be wrong], though just as mean as their bigger cousin! The African Buffalo, one of my favourite animals of all time, true definition of "animal power"!!!
cheers,
