The problem with that is, you are only invoking it on login.
This together with

suggests you are logging from your root user back into your
normal user, never logging out of these shells, and the
older shell processes are hanging around, like this:
$ ps
PID TTY TIME CMD
18672 pts/0 00:00:00 bash
18689 pts/0 00:00:00 ps
$ su -
Password:
ra:~# ps
PID TTY TIME CMD
18690 pts/0 00:00:00 su
18700 pts/0 00:00:00 bash
18704 pts/0 00:00:00 ps
ra:~# su - jon
Password:
$ ps
PID TTY TIME CMD
18672 pts/0 00:00:00 bash
18705 pts/0 00:00:00 su

18739 pts/0 00:00:00 ps
What you really want to do is execute some code as root on
logout. One hacky way to do it is to call reset in root's
logout script:
$ sudo su -
root promptroot@~# cat .bash_login
export PS1='root prompt\[\033[0;31m\u@\w\$\033[0;30m \]'
root promptroot@~# cat .bash_logout
reset
root promptroot@~#
<screen clears>
$
This is a bit slow, mind, if you really want to change the
text colour for the root user then you should "unwind" the
control characters instead by preserving the older PS1 and
keeping track of which control sequences you've "opened":
~root/.bash_login:
export OLDPS1="$PS1"
export PS1="whatever you want"
~root/.bash_logout:
echo "control chars that reset the text colours"
export PS1="$OLDPS1"
