Text or Background Color Change

Here is a script we currently use.   Mgmt is now wanting the text and/or background to change color instead of the Font changing size.

Is there a way to do this?

#include <Date.au3>
#include <File.au3>
#include "array.au3"
#include "String.au3"
#include <Sound.au3>
#include <Constants.au3>

Opt("TrayMenuMode", 1) ; Default tray menu items (Script Paused/Exit) will not be shown.
Opt("WinTitleMatchMode", 1) ;1=start
;HotKeySet("^z", "Terminate"); Press Ctrl z to terminate script
