CTRL-D is new to me. Thanks for the trick.

It works for me. I use this:
/root/.bashrc
export PS1="$(tput setaf 1)[\T]$(tput setaf 1)[\u@\h]$(tput sgr0)\w$ "
/home/stan/.bashrc
if [ "$PS1" ]; then
PS1="$(tput setaf 2)[\T]$(tput setaf 2)[\u@\h]$(tput sgr0)\w$ "
fi
When I from su the prompt color is back to that defined directly above for user
stan.

I use this as my reference. Not a bash manual, but works for me:
