My dad is also in his late 60s and his beard and temples started going a gingery colour a few years ago. I think if your hair is a certain colour and starts losing the pigments it will look kind of gingery before turning grey. Thats what's happening to my dad anyway. Get him some Just for Men if he's not happy with it.
a similar thing happened to my dad but it turned out he had been regularly slapping aftersun on his face and head after being on the golf course. Unfortunately my mum had bought one that contained tan prolonger/fake tan. As mentioned in other postings it looked like he was a heavy smoker and the grey hair had got quite discoloured and gingery!!
