The term 'synaesthetic' can be used to broadly describe the different kind of association that the ancient Greeks made between the five senses. 'If colours are the external manifestations of objects, then the perception of that colour can tap into other ideas such as smell, liquidity, saturation, touch, texture.'. In what we would tend to think of as purely visual, the ancient Greeks brought other senses into play.
Universal Product Code. The Universal Product Code (UPC) is a barcode symbology that is widely used in the United States, Canada, United Kingdom, Australia, New Zealand, in European and other countries for tracking trade items in stores. UPC (technically refers to UPC-A) consists of 12 numeric digits, that are uniquely assigned to each trade item.
The NRF Standard Color and Size Codes are not part of the UPC. A UPC is a 12-digit code that includes the 6-to-10-digit vendor id number assigned by GS1, the 3-to-5-digit product id assigned by the manufacturer, and a final check digit.
