Secret behind Toothpaste and Colour bars.

It's certain quite a sensible number of us don't know this. Though we see it day in, day out, that is, for those who are regular tooth brushers, we think of it as though it was for the aestheticism of the
tubes.

I need not call our observation to this, it's something we regularly see. Looking at the bottom of our toothpaste tubes, there are colour bars inscribed on them. They range from blue to red, to green, to
black, but the question is, do we really know why these colour bars are there in the first place, and
what each one actually mean? Here is it:

* Green: Made purely of natural material;
* Blue : Natural + Medicine;
* Red : Natural + Chemical composition;
* Black : Purely chemical.

Don't start casting blames on your overdue ignorance, you're not the only one in that pair of shoes. This piece of information was never true in the first place.

THE TRUTH

Yes! The colours actually mean something, but what exactly is it?

The rectangular marks or lines on the tubes referred to in the message, are used in the packaging process. The marks are known in the packaging industry as "eye marks" (or sometimes "eye spots"). They do not in any way indicate the chemical content of the tubes they are displayed on, regardless of what colour they are. That is not their role.

Eye marks can be identified by electronic eyes used in sophisticated modern packaging machinery. The marks serve a variety of packaging purposes such as telling the machine where to cut and crimp tubes or indicating the desired colour of print on packaging. Many products have such eye marks, although they may not always be visible to consumers as they are on tubes.
