Meaning of The “Secret” Colour Codes On Toothpaste Tubes


The square color codes at the end of toothpaste tubes and their meaning are something that has circulated on the internet for some time now. People make these into pictures (see below) and share on the internet with the aim of enlightening people. I have seen this on Facebook, Instagram and people’s display pictures on BBM and WhatsApp.

Below are the color codes they claim to be available on toothpaste and what they say they mean. They talk about the composition of the toothpaste. The color marks come in square and rectangular shapes.

What The Colour Marks At The End of Toothpaste Means According to Them

They try to tell people that the colours at the bottom of the toothpaste tube shows the composition of the toothpaste itself. Below is one message I got as broadcast on WhatsApp. The person also used the following as the display picture to press home her point.

Pay attention when buying toothpaste, at the bottom of the toothpaste tube there is a color bar. And do you only know the original meaning of the color bar! Try to choose green and blue, there are four kinds:

Green: natural;

Blue : Natural + Medicine;

Red : Natural + Chemical;

Black : pure chemical.

In fact, there are different versions of this and they sometimes contradict one another.

The intentions of those spreading this news are good because they aim to educate the “ignorant” customers about these things so that they make the right choice while buying. The problem with this, however, is that the they have got the facts really wrong.

Colour Codes On Toothpaste Tubes; What They Truly Mean

The colour marks on the toothpaste tubes are in no way indicating the composition of toothpaste. In fact, when you are saying that something is natural and something is medicine, cant you have something that is both natural and medicine?

You might be very surprised to find out what these marks are. If one thing is sure, it is the fact that these marks do not tell us anything about the composition of toothpaste.

So, what do they stand for then?

There are different colors as you might have seen. There are red, blue, red and black colors and they are nothing but eye marks. As someone who has worked in a multinational production factory — packaging development to be precise — I know that these are eye marks.

So what are Eye Marks on Toothpaste packaging tubes?

According to bestpkg,  eye mark is a machine-recognizable mark, printed on web-fed packaging materials. The eye – mark is the reference point from which the machine will register other operations such as further decorations, heat sealing, or package cut-off.

In clearer terms, when products already filled in tubes or sachets are to be sealed, the eye marks are there to tell the machine the point at which the particular tube or sachet ends. The machine, depending on what it needs to do would then either seal the package and/or cut it off that point.

If you look at other products like creams, milk sachets and beverages packed in sachets, you might just see them there too.

Okay, while writing this article, I quickly looked around my room and my kitchen and I saw some items with eye marks on their packages. So, I am going to use them as examples and correlate the color of the square or box-shaped marks on them with what is being circulated.

They say that black color means that the product is a pure chemical. How wrong could this be? I have black marks on all the products I am going to show you here.

Here is a Lubriderm Cream Tube that I found in my room;

It has a colored black mark at the end.

Here is an Indomie (Noodles) sachet with a black mark like that too.

Is this Noodle purely from Chemicals?

Okay, look at my natural Ginger Drink sachet.

According to those that made those images, this ginger drink is a pure chemical.

Okay, one could argue that a cream could be made from chemicals as well as natural ingredients. The same argument could hold for the ginger drink too but what about the Noodles?

What about the products I am listing below here too?

This is a thyme sachet. Is there a way thyme could be made from chemicals?

Below is a Spaghetti sachet with the eye mark too.

I am still looking for that research that confirms this Spaghetti could be made from pure chemical compounds.

Before we believe some claims, let us do some research about it. Even if the person making the claims has backed it up with facts and evidence, let us still confirm them.

This is not purely a food article but it’s something that enters our mouth and since these marks are available on foods too, it’s only a matter of time before they start labeling foods as natural, medicine and pure chemical because of the marks.
