Window titles and console colors are handled inside the xterms, not outside. There is a special escape sequence to set the window title for instance, which your servers might be using already for all I know.

For instance, my profile has PROMPT_COMMAND set to

Code:

echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\007"

...which sets the window title to username@host:/path/to/currentfolder every time it prints a prompt.

It also has PS1 set to

Code:

\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\]

...which causes it to print colored prompts like

Code:

username@host ~/path/to/folder $command

This is specific to the BASH shells. If you're using other shells it may be configured differently.
