Assuming "non-flying" means no spinnaker, then you had the pole on a winged-out 150 genny, which then filled forward of the headstay because your capt left the pole up too long, and started to round up to windward as soon as it was released. Result is a big jib that's filling wrong-side-out in front of the headstay rather than vice-versa.
Not much you as crew could've done. If you had a sheet lead forward of the headstay, then maybe skipper's advice would've worked, but I'll wager you didn't. So it's very hard to pull that sail back against itself so as to get it to fill on the "correct" side.
You were fighting the wind, and the wind was stronger. Colored sheets may help in general, but not here.
If I've misunderstood the situation factually, then I recant.
