ScrollingMessageFrame:UpdateColorByID(id, red, green, blue)

Updates the color of a set of messages already added to the frame. Used in the default UI to allow customization of chat window message colors by type: each type of chat window message (party, raid, emote, system message, etc.) has a numeric identifier found in the global table ChatTypeInfo; this is passed as the fifth argument to :AddMessage() when messages are added to the frame, allowing them to be identified for recoloring via this method.
