Leigh,
I did a trip there in march this year, and apart from being am awesome trip, which I am sure you are glad to hear!
I can tell you that none of us brought any green Poppers home they are all now decorating the reef. I am certainly no expert but as a report on what happend for us, Green was a standout colour. In fact I waited two days before pulling my first green one out, and smash first cast!!!
