I suppose you mean "without being initialized".
Not executing the then-part implies that `specified_bg' was a Lisp
string and `mac_defined_color (f, SDATA (specified_bg), &color, 0)'
returned non-zero (i.e., negation of the condition). In that case,
`color' is initialized by the `mac_defined_color' call.
