I feel like part of the movement towards grayscale is that people are afraid to stand out. I can always easily find my car in a parking lot, because it stands out. People can find me in a group, because I stand out. I'm glad I don't care too much about the opinions of other people, so I just wear what I want to and don't try to blend in. I also feel bad for people who don't wear what they'd like to because they're afraid to stand out, because you only get one lifetime.
I personally also hate that the already dreadful winter is made even more dreadful by everyone wearing dark clothing. Please all buy something colorful to wear next winter... It's safer too!
