Hair color product web sites offer the entire range of hair color available with them and what can be done with it. However, do remember that they are using professional models (with amazing skin) and you would need to discount some of the ideas that they demonstrate. The official web site however, does help you get the right shade and that is very important before you decide your hair color.
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!
