Nice. But this setting should be check that we have a terminal first isn't ?
Some test like this before

test "X$$TERM" != Xdumb \
&&  test -t 1 2>/dev/null  \
&& ....

and in reality this echo use is not portable.

In popt 1_17 autogen.sh does

red=; grn=; lgn=; blu=; std=;
test "X$$TERM" != Xdumb \
&&  test -t 1 2>/dev/null  \
&& { \
  red='^[[0;31m'; \
  grn='^[[0;32m'; \
  lgn='^[[1;32m'; \
  blu='^[[1;34m'; \
  std='^[[m'; \
}

and

Die()    {
        color="$red"
        echo "${color}${_PROGNAME}: Error: $@${std}" >&2
        exit 1
}

Die "message here"

or the inverse logic. This is what automake  and popt autogen.sh does.
