Samsung UK lists a new brown color option for the Galaxy S6
11
Nobody mentioned anything about an eventual brown/bronze version for the Galaxy S6, though, but it appears as an option over at Samsung's UK site, as you can see from the screenshot. Granted, you can't really choose this color yet, so it might be a glitch, or, alternatively, Samsung might be readying to announce another color option later on, as it sometimes does.
