Most often, we do not understand the inscriptions and indications on items we buy from supermarkets and shops. One of such item is the toothpaste.

Almost every brand of toothpaste (Colgate, Pepsodent, close up, Oral-B, Rembrandt among others ) tube has squares coloured red, green, blue, or black which is also referred to as the “eye mark” at the tail end of the toothpaste tube.

However, there have been many stories and myths about this “eye mark” at the tail of the toothpaste. Some people say it indicates what chemical is used in making the toothpaste. Some stories says a green mark means the toothpaste is all natural,
a blue mark means it contains a mix of natural ingredients and medicine, a red mark means it contains natural ingredients and chemical ingredients, and a black
mark means it contains all chemical ingredients.
