The Pillow Book

"The Pillow book" is a movie. It is about a person quite obsessed in writing on bodies. But the thing i remember the most is the book she was reading, about a person that had lived in China, in the fifth century, or something like that. This person would make lists, like, "the best colors to wear". I remember that the best one of them all was indigo. And i find lists of useless things fascinating after this movie.
