Este post no es un manual para cambiar el color de Prompt de linux; no es mas que una orientacion de lo que se puede hacer.
En la red hay cantidad de manuales sobre ello.
Aqui os dejo una pequeña muestra de como empezar.

Secuencias de escape ANSI: colores y movimientos del cursor

Por ejemplo: poner texto azul en el prompt:

PS1="\[\033[34m\][\$(date +%H%M)][\u@\h:\w]$ "


Negro 0;30 Gris oscuro 1;30
Azul 0;34 Azul claro 1;34
Verde 0;32 Verde claro 1;32
Cyan 0;36 Cyan claro 1;36
Rojo 0;31 Rojo claro 1;31
Púrpura 0;35 Púrpura claro 1;35
Marrón 0;33 Amarillo 1;33
Gris claro 0;37 blanco 1;37

Para que tengais una idea este es el script de mi prompt:

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

# don't put duplicate lines in the history. See bash(1) for more options
#export HISTCONTROL=ignoredups

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# make less more friendly for non-text input files, see lesspipe(1)
[ -x /usr/bin/lesspipe ] && eval "$(lesspipe)"

# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "$debian_chroot" -a -r /etc/debian_chroot ]; then
debian_chroot=$(cat /etc/debian_chroot)

# set a fancy prompt (non-color, unless we know we "want" color)
#case "$TERM" in
# PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
# ;;
# PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
# ;;

# Comment in the above and uncomment this below for a color prompt
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\t \[\033[1;35m\]\u@\h\[\033[00m\]:\[\033[01;32m\]\w\[\033[00m\] $ '

# If this is an xterm set the title to user@host:dir
case "$TERM" in
PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD/$HOME/~}\007"'

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

#if [ -f ~/.bash_aliases ]; then
# . ~/.bash_aliases

# enable color support of ls and also add handy aliases
if [ "$TERM" != "dumb" ]; then
eval "`dircolors -b`"
alias ls='ls --color=auto'
#alias dir='ls --color=auto --format=vertical'
#alias vdir='ls --color=auto --format=long'

# some more ls aliases
#alias ll='ls -l'
#alias la='ls -A'
#alias l='ls -CF'

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
#if [ -f /etc/bash_completion ]; then
# . /etc/bash_completion
