My natural hair color was somewhere between honey if I was indoors and a new penny if I was in the sun. Lots of color variation. My family grays early and for the longest, the grays just looked like highlights. Then I got too many. And sadly, the red hairs went away first, which just made it blah. I began coloring the front roots only, because I don't care what's in back. I still do the front and part every two weeks, because my hairs grows FAST. I will color it until I am in a casket, and someone else had better do it then. I'm one of those who can pass for 10-15 years younger than I am because I have a younger child and few wrinkles. But if I let my hair grow out, that assumption would be gone. Gone. I think people with dark hair gray nicely because their coloring suits it. Blondes and redheads don't usually fare as well. I'd just look washed out.
