Transparent Drink Labels

From looking at these two websites Pichaus - Shared Pictures and Dieline Packaging I found a few interesting transparent labels. I mostly focused on the layout, simple imagery and type used. the majority of these designs use one or two colours of the same colour but different shades. Making it simple as possible but still making it attractive and impactful to the viewer. I need to think about this when applying my transparent design to the bottle and need to think about not getting it lost with the liquid inside the bottle and also with objects around when its situated in context.
