 The color red is prominently seen in all four segments of the film.  For example, Yussef, the Moroccan boy who accidentally shoots Susan,  wears a red jacket that says "Morocco" on the back, while Amelia  wears an elaborate red dress, causing her to stand out; Chieko  frequently uses a red pen to write notes to people who cant  understand sign language, and the seats on Richard and Susans bus  are red.
