Is A Hoax - Colour Squares Do Not Denote Content Of Toothpastes

It has been widely circulating online about that the color squares appear on the tubes denote the content of the toothpastes. It is something like:

Green: natural;
: natural + medicine;
Red: natural + chemical composition;
Black : pure chemical.


The squares, called "eye marks", are marks used in the packaging process. They tell the packaging machines when to perform certain tasks such as detecting and aligning squeeze tubes, cutting or crimping tubes.

I guess the answer is not as interesting as the "color squares reveal the content of toothpastes" but it is just a simple fact. Hope that it clears out some of the online myth.
