Black and white

I'm sitting at home, watching Sin City, all black and white with little splashes of colour and everything. This reminds me of childhood memories, watching old black and white movies and new colour movies and coming to the conclussion that the whole world used to be black and white "in the olden days". To me, at such a young age, this seemed reasonable because all the black and white movies were set in the past and all the colour movies were set in the present. Thank god my train of thought never included silent movies(!)
