Technically I think I'm an autumn, but I don't like very many of those colors on me. I feel decidedly un-vibrant in most browns, and in general I dislike muted, muddy tones. I prefer black, purple, true red, and love bright neons.
I remember reading one time about a few certain colors that look good on everyone, I think one them was called "Indian blue"? and I do like this color a lot too.
I'm not sure how I arrived at my signature colors though, it has been an evolution of style in general, and along the way I've found the ones I like and don't like. The ones I like may not even be what look best on me but that matters less to me than how they make me feel
