During winter now, I notice I like grey, black, white, pink, and purple frequently. I don't know if I would really say I have a signature color. I have the tendency to notice I don't own clothing in a certain one, then I decide I have to get some items in that color. Recently I want things in navy blue, but my interest in navy blue started a couple of years ago after seeing pictures of Lily Cole in a navy blue tank dress and more recently Charlotte Gainsbourg in a navy blue tshirt. I might also want more yellow.
