Industrials comments: I just found out my father has black & white condition. That is purple. Light purple at the white middle almost. Very light. The hair is the real black, correct. This character is name to do with Purple. There is America saying one of those indigo child rumor, has something mars, or something purple I bet.

You can intuitive reading the black and white words in the script introduction like Wiki. They have expert like a real Librarian, like me, doing that....perhaps, to say, which important point, you select one character you want to work on. One character.
