    "darkred", "lightgreen", "green", "darkgreen", "lightblue",
      "blue", "darkblue", "brown", "cynober", "purple",
        "darkpurple", "lightgray", "gray", "black"};
  if (BodyParts.index( tokens[0]) > -1 && BodyColors.index( tokens[1]) > -1) {
    if (tokens[0] != "all") player.colors[ BodyParts.index( tokens[0])] = tokens[1];
    else {
      for (i: BodyParts) player.colors[ BodyParts.index( i)] = tokens[1];
    }
    player.chat = "Changed " @ tokens[0] @ " to " @ tokens[1] @ "!";
  }
} 


PHP Code:

 if (BodyParts.index( tokens[0]) > -1 && BodyColors.index( tokens[1]) > -1) 


What does the -1 do? Assuming its the word number, how can words be less than first word (which is number 0).

PHP Code:

for (i: BodyParts) player.colors[ BodyParts.index( i)] = tokens[1]; 


What does the "i" do? My guess is its a variable?

Lastly can SPC be used instead of "@"?
