Actually the pale horse is really the green horse - the Greek was chloros. Some people have noted these 4 colors (white, red, black, green) are the Pan-Arab flag colors.

They're fictional characters in the book of Revelation: white (conqueror), fiery red (war), black (famine), pale (death). If this sound interesting to you, the Nine Nazgul of LOTR have far more literary value.
