The second stop on the internet is an Expert's page....most likely to be on lifestyle web sites which tell the ground rules of which skin types goes with which hair color etc. Don't bother to read too many of these as each one of them is likely to have their own version of hair color palette! Once you have short_listed a range of hair color options, try looking for pictures of people with similar coloring and how they would look in it. Many salons have sophisticated software which helps conjure up an image of you with the hair color and it might be worth the money you spend on it.
But any such stigma associated with coloring our mane is long gone. Anymore it's so common no one gives it a second thought. In fact some of us would be hard pressed to recognize our own natural hair color it's been so long since we have seen it. Because as they say color is a girl's best friend.
