I've also stolen coloured PS1 values from my current Gentoo-box, & they
use the '\033' escape-sequence listed above, but in full, not through
variable-names. They also define 'normal' as "\[\033[00m\]" (not sure of
the difference).
However, Gentoo define them in /etc/bashrc, & have the line ".
/etc/bashrc" (that's 'full-stop' 'space' 'filename') in /etc/profile,
instead of a PS1 declaration. I found this to be necessary when booting
into my LFS system. I also have a third colour defined for
package-users, but that had to go in the pkgusr ~/.bashrc to work,
presumably because they never boot the system, they are only su'd to by
root.
There are additional pre-checks for the existence of /etc/dircolors &
that the terminal in use supports colour. For future builds, it's my
intention to incorporate this into my base LFS-build, as dircolors is
installed by coreutils fairly early in both chapters 5 & 6 - i haven't
worked out the details yet...
