You can be neutural, you know!
Not every one falls into the Warm/Cool "thingy".
Have you tried trying wigs on? Or trying some hair pieces in the mirror at your local beauty suppliers?
My opinion is that you look from the photos as if ashy (i.e. little or no red) would suit you, but I'm very opinionated & only right 50% of the time!!! (on a good day...)
I also feel the need to say that I think you look fab in your pictures (ok, 'cept maybe the last one....)!
Good luck with the hair!
