How can I set window titlebar text font and color?

[grosner]

I realize I can use WinSetTitle to set a window's text.

• Is it possible to set a window's (e.g. Notepad.exe) title bar font and text color?

• Can the font and colors be limited to only a portion of the window's title bar text?
  
  My use case is to to put a colored mark on the window title bar text while my Autohotkey script is running, similar to what was described here: viewtopic.php?style=19&f=76&t=99039

Hallo,
unfortunately this only runs with Guis.
I wanted the Windows XP design and so I made this one. It consists of four Guis each.
