/me runs the script

AUGH!!  my eyes!!  what a visual abomination!  what is this, a Tk  
program from 1994?!?

seriously, have you heard the party line on setting widget colors yet?

Both of which point to http://ometer.com/gtk-colors.html


But to answer your question directly, the widget state you want it  
"prelight".

That's because an hbox is a no-window widget, and doesn't actually draw  
anything.  The same goes for the frame; notice you set the bgcolor of  
the frame to red, but the only part of the frame that is red is the  
outline --- which is the only thing that the frame actually draws (on  
its parent's window, at that).

An event box has a window, and this setting the bgcolor for it will  
cause something visible, but because of how children are packed into  
frames, you will probably find this not very visually appealing.

by the way, only one of these is needed.  the default handler for  
delete-event destroys the window, so destroy is usually sufficient.
