I'm glad to hear Apple is offering more color choices. They sell so many iPhones, that they should make more of an effort to offer variety.
As for the colors themselves, I'll wait to see it in person before declaring my opinion. So much can depend on the lighting of the photograph. Even if I don't like a color, so what, others may love it - to each their own. Choice is great.
For those complaining about innovation: first, there is much more to these phones than just the color, so to judge Apple on their lack of innovation because you don't like one color is silly. Second, everything involved in making something like an iPhone involves innovation and pushing the boundaries of technology and manufacturing. Who knows how much effort went into making sure the colors were just right, my bet is a lot of effort.
All that said, I kind of like what I see in the gold pictures.
