I don't believe that Susan E. Hinton ever mentions the name of the high school that the Socs and greasers attend in her novel, The Outsiders. It is simply called "our school" when Ponyboy tells the reader that Cherry is a cheerleader there. In the sequel to The Outsiders--That Was Then, This Is Now--in which Ponyboy also is a character, the high school is given no specific name. As for school colors of the greasers, none are given, but I think they would have considered black (or perhaps black and blue) the only possible choice.
