Just a thought, sometimes people dye they hair a colour that doesn't suit them and this is where a lot of confusion about "what is my season" arise. Look out for your natural hair colour and make a decision. You may go back to colour which is close to your natural and look better.
Hmm the Personality Café thing looks interesting - but I've seen several self-diagnostic sites showing celebs and putting them into seasonal categories. Trouble is, it only goes to prove you can't guess at it by looking at someone; I've noticed several of those women have been 'diagnosed' as being at least 2 different seasons. Indeed, my DM, who is a Winter, would not be diagnosed as such from that site as her eye colour doesn't appear in the Winter descriptors.
