I don’t know the bottle but if you don’t have an airbrush, hand painting the cake will result in a shiny surface. You’ll need to experiment mixing colors – a mix of brown, yellow and orange I’d think – to try to get the color you need. Paint a sample on a white piece of fondant and also on a tan or yellow piece. As I said I have no idea what the bottle looks like but to get a mosaic-like finish you can either put together pieces of fondant (like a true mosaic) or trace the design and emboss it with a pointy tool of some sort, and paint within the lines. If you need to you could outline the shapes with a darker color if that’s what the design calls for. Good luck.
