just tried this function with bash -
and, yes, the 'e' *is* required
to expand those octal codes aka
"(backslash) escaped characters".
thanks for catching this!

never noticed because the zsh
has a built-in "echo" command:

  zsh>  which echo
  echo: shell built-in command

=== corrected version of _colortest

_colortest () {
        echo -n TEST1:
        for i in 30 31 32 33 34 35 36 37
        do
                echo -en "\033[${i}mColor ${i}\033[39;49m "
        done
        echo
        echo -n TEST2:
        for i in 90 91 92 93 94 95 96 97
        do
                echo -en "\033[${i}mColor ${i}\033[39;49m "
        done
        echo
}
