Minor detail: Salt and Pepper hair?

Apparently people age really fast on Zwift! For those with darker color hair you basically have to choose between solid dark or gray, with no in-between. I would venture that most people who don’t dye their hair have a good 10 years (prime, subscription affording years) in which their hair color is what most people call Salt and Pepper. I know this is a small detail…but how hard can it be to make it happen, Zwift? 

For the auburn beard too, please!

 I too suffer the indignity of an inaccurate avatar, without my mid-life crisis dyed pillarbox red hair and big hook nose. Oh the humanity!
