Avoid making significant changes to the shapes or materials of the boxes and jars, as the focus should be on graphic modifications. Refrain from using dark or monochromatic color schemes and avoid evoking a vintage feel in the design. Do not incorporate photographs or intricate illustrations that may detract from the brand's youthful and modern image. Ensure that the new graphic does not overshadow the brand's coat of arms and name, as they should remain recognizable and integral to the overall packaging design.
