What do you think about "season appropriate colours"?

I had a difficult time with depression and anxiety last winter, and this year find myself being drawn to wearing pale colours and prints, even as we head into the colder months. I think it may be my subconscious trying to protect me from the wintertime blues.

Do you think it looks incongruous when people wear light colours in winter? Or in the same vein, do people dressed in black during summer look out of place? Do you find that the colours you wear influence your moods?
