I know it's been a really long time since I've watch DS9 (I really want to again too), but that if there's one thing that spending over 3 years on TVtropes.org has taught me, it's that there is nothing subjective (questionably opinionated) about character dialogue that is part of the script. It is canon because it was written, recorded, and heard in the episode. In this case, Kira saying that Bajor has green oceans. She was stating it as a factual statement, and I think the planet was actually shown a few times on screen as well.
If I'm reading this thread right, the suggested "Official" picture of Bajor comes from an art book that was released after DS9 had ended, making it supplementary material that can't be taken as a bigger truth over spoken dialogue heard in the series.
I really believe that dialogue takes precedent over visual imagery in this situation where both can be accurately proven which actually came first. If Bajor was shown to have not-green oceans before that episode where she said it, then I'd take back everything I stated above and would support the image since it would have come first.
meh, one of a thousand times Star Trek contradicted itself.
Nothing in ST contradicts anything else, it all matters which "reality"/version/series/film/etc. of ST you are currently visiting. I mean, jeez, just how many times have they broken official history and it made changes to their visible/current timeline?
They had to let poor "Joan" die to save the Federation but "old" Spock just let the new timeline happen to him in the last movie. Maybe with great age and wisdom comes less caring just how badly time/history/reality gets messed up.
The only true rule of canon for ST is this: Whoever is writing whatever version(s) of ST is (are) currently active sets the current canon until someone after them changes it.
WTH, how did I get on this rant? *looks at Taco and shakes fist*
Trek has always contradicted itself. Everything from ship sizes, to the current stardate. Sometimes production had to make modifications based on what was going on at the time so that it would make more sense on camera. Along with different writers, or whatever else managed to happen. Heck look at The Motion Picture. How big was the Veg'r cloud really? It got changed after it was remastered.
