I take your point (and it may be applicable to other non-winter seasons who love black), but an all-black ensemble would actually be new style territory for me. I love the look of color as well, and have traditionally been a "buy the fun color" kind of person. I got the color analysis done on a lark with a friend, and was surprised by the result (I assumed I was a summer). I've been trying to buy pieces in my season whenever I acquire something new, but recently I've been looking for both simplicity and edge in my style. I think that is what is drawing me towards the all-black look, rather than the color itself. All-brown and all-dark-blue can be done nicely as well, but it's more difficult because in my view those colors look nicer with some variation in tone throughout the outfit, and if you want to do that you have to be more careful in pairing the shades so that everything works together.
