Packaging Design Got One!! Wild Mullet Catch FOOD PACKAGING by Ching Wei Liu Mullet fish roe is famous as a true delicacy. The packaging design with its premium appearance focuses mainly on the use of black as a color to visualise the fact that this fish is named for its black backside. In addition, the color concept aims to picture the specific atmosphere occurring during the fishing season, as the coastal fishing villages are then covered with the golden light of mullet fish roe that have been laid out to dry. For this reason, mullet roe is known as the black gold of the sea.
