The Truth Revealed! Here is What the Colored Squares on Tubes Really Mean

Eye Marks

Actually, the squares present on tubes are marks used in the process of manufacturing. They are known as “eye marks” and are read by a sensor so they can detect and align squeeze tubes.

Usually the square color is a color of something else too which is printed on that side of the tube. For example, the tubes of Crest toothpaste often have blue writing and matching blue eye marks on the back of the product.

This means that the printed squares on the tubes are not related with the chemical makeup of the product inside. It is only an eye mark used by sensors in the manufacturing process. The available color used in the artwork on the tube chooses the color of the eye mark.

If you think the graphic shows real information, check those products who have greet square on their packaging and you will find out that they all contain chemicals.
