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.
Some of the most interesting hair color ideas, however, do not come from professionals but from celebrities who sport unique looks to stand out in a crowd. Not only do they manage to start off a fad, they also help create some very interesting hair color ideas. So if you have a favorite movie star you associate yourself with, you can always check out the hair colors they have sported now and in the past. Try not to choose a hair color idea which does not suit your personality as that is something you will be very uncomfortable in once you get it done!
