I think it all depends on whether you're fair-skinned or slightly darker. My wife is a hairstylist and she's been trained to suggest different hair colors for ladies of all ages depending on their skin tones. Mind, she's Japanese, and the Kansai area is famous for middle-aged ladies having blue or green-dyed hair...don't ask.
I'd go with brown or even a touch of auburn and red in there. Black, even if it's skillfully done, always looked like magic marker on a middle-aged lady or man (if you are in the mid-fifties and I have no idea if you are or not so don't get angry, 'kay? Okay.)
JMO.
