That makes sense, and I suppose, as you say, the more direct thing is to 
manipulate the terminal, tho that means a restart anytime you wanted one 
of those color changes, and my xfce4-terminal doesn't seem to permit 
command line color changes anyway.  But to the extent that zsh supports 
color, shouldn't the colors stay set until they are explicitly changed?  
I see in bash:

echo -e "\e[41m"
red
red
red
echo -e "\e[0m"
normal
normal
normal

I get exactly what I ask for--when I want to return to defaults, I say so.

So, would it be possible to have, say, an option to stop ZLE from 
clearing the screen as it does?  I can see that the zsh way is safer, 
but being able to turn it off sounds like a cool option as well, and 
friendly to our bash converts besides.
