I have Konsole set (via its Menu Bar "Settings"->"Edit Current Profile") to white text on black, but any changes apply to all sessions, not just the local one. I would like a background (eg dark grey) in SSH sessions that is different from that of other PCs on the network, so I can see at a glance which one I am using.  Fiddling around with the PS1 variable in .bashrc in the remote PC I have only succeded in changing the background colour under the text itself, not the whole background.
