I actually just received the rust in the mail today and it's different than how I'd pictured it. I'd previously seen a picture of it and it had looked like a bright orange-red - IRL, it's more of a bright (very bright) maybe pumpkin-color orange - I don't see as much red in it as I'd thought there would be. It will probably be a color that people either love or hate and it will also be difficult to match with clothing. I adore it, but it probably won't appeal to everyone.
The green is different than I thought it would be too - maybe a little deeper than the bright emerald I'd pictured. And the beige/camel color is basically just a slightly darker shade than the Fall 2005 Caramel.
The leather on these is not the greatest - still pretty shiny and veiny (and my SA hand-picked these, so I can imagine how bad some of the others might be), so keep that in mind if the newer leather bothers you.
