Sure. The colours come from a set of files by hostname:

$ cat /var/local/lib/myhosts/colours/axis 
5 magenta bbarbutton=white,magenta,none:bbarhotkey=magenta,white,none
$ 

5 is for ANSI colours,
magenta is for, eg emacs, mutt, etc,
bbarbutton is for mc.

The lines from /root/.bashrc are:

if [[ $- = *i* ]]; then

    export PROMPT_COMMAND='Myprompt="$? " && [ "$Myprompt" = "0 " ] && Myprompt=""'

    # read value from file, and sanitise it
    Hue=$(head -c 1 /var/local/lib/myhosts/colours/"$HOSTNAME")
    if grep -q ·"$Hue"· <<<"·0·1·2·3·4·5·6·7·8·9·"; then
        PS1='\['$(tput setaf 3)$(tput setab 1)'\]$Myprompt\['$(tput bold)$(tput setaf 7)$(tput setab "$Hue")'\]\H \t \w\['$(tput sgr0)'\]\$ '
    else
        PS1='—$Myprompt—\H \t \w\$ '
    fi

    #hexdump -C <<<"$PS1"

fi

Cheers,
David.
