When I was a child, blue was my color. I still like it, it's so calming and pleasant.
But from some time to now, I love red. It's a great color: it's the first color we see, it's the color that represent both life and death, love and hate, revolution, movement, change, activity... It's so ambivalent and disquieting.
Not all the days I'm in the mood for red stuff, but I love it (in fact my nickname means "red" in german).
