I think it's important to not get too caught up in what "color" zone you're in, especially as a direct correlation to what/how much you can see. The demarcations are blurry and suspect anyway, as Mr. Flanders keeps pointing out. I've seen the horsehead nebula from the orange--can't be too bad. I think if one can see the Milky Way at all there will be plenty to observe.
