Todd, as Greg wrote earlier: 'In X11 the
window manager is in charge of the window decorations (frame border,
title, etc.). For ctwm(1) the "TitleForeground" and "TitleBackground"
lists are used to set the colours of the window titles.'
You can set the title TEXT from Resources, from the -title option and even
change it through output INTO the xterm using one strange escape sequence as
mentioned a few times earlier, but it is only drawn by the window manager and
not using the terminal emulator of xterm, so no colours that way.
