I've not used the combo tests much myself, but my understanding from
combo.cfg(5) is that blue is equivalent to a red, so as long as your combo
test is defined to stay green if at least one thing is up it would stay
green. If the secondary also went down (either red or blued out), the
combo test would then go red.

I think.
