I personally use
    RPS1="%(?.."%{$'\033[33m\033[41m\033[1m'%}"%?"%{$'\033[0m'%}")"
, but it will draw the exit code only in next prompt (and only in the last one).

Can I ask how are you going to modify existing prompt? I know a way to modify 
the current line, but I don't know what to do if I want to modify the line after 
LF was fed to the terminal.
