The executable file does not pick up whichever start-up file it is in
which you are doing something like

autoload colors
colors

so $fg is not defined.  I'm guessing it's .zshrc.  If you move this to
.zshenv it should work (unless you are explicitly suppressing that with
the -f option).

The second set, being raw escape sequences, are always interpreted by
the terminal.
