I just figured out what season I probably was by visiting online sites. I think I am a Deep Autumn. Back when there were only four seasons, I couldn't figure out what I was, because some stuff from Autumn fit, but so did some stuff from Winter. Likewise, there were some real no's in both those seasons. So it makes sense that I would be a Deep Autumn, since I am between the two.
I recently did the color analysis in the Triumph of Individual Style book. That is interesting. It's not based on seasons, but you check your skin, hair, and eyes against certain color charts. That analysis made me realize why I can wear both warm and cool colors: I have neutral skin, warm eyes, and cool hair. That book might be worth a look also, just to give you more information.
