Dan sat on his bed and looked around. Everything around him was black and white. The posters on the walls were black and white. The clothes he wore were black and white. He ran his fingers over his black and white duvet, feeling how soft it was. "What is color?" Dan thought to himself. "Caspar said you could see it. But what is it? When I look around I see only the lightest shade of light and the darkest shade of dark, and the shades in between. This is not beautiful as Caspar said."
