If you want to add a little something to your hair, you would look amazing with a medium auburn. I would pick a red with a maroon/brown tint, not orange and not plum. It will bring out your eyes and compliment your fair skin.
I don't fit with any of the charts that tell you if you're warm or cool... or summer or fall. I just go by holding things up to my face to see what really looks the best with my skin, hair and eyes.
