What is the real meaning of the color code? The tiny symbol on the sealed end of the tube often comes in blue, green, red, or black. Some say the color codes represent the chemical content inside the toothpaste.

With using this theory,

  • Green color code means an entirely natural toothpaste.
  • Blue means the toothpaste is a combination of natural and medicinal ingredients.
  • A red code means natural and chemical ingredients.
  • A black code means the toothpaste is made of all chemicals.

This is just a myth, and it should be treated as such. The truth is, the colored squares are just a part of the manufacturing process. The colored codes are referred to as “eye marks”. It is called an eye mark because an electric eye can only read it.

The code contains hidden information that can only be read with a light beam sensor. These codes can also be seen in other products. The information in this code tells machines where the packaging needs to be cut and folded.

Is it a hoax?

While the rumors and myths about the toothpaste color codes are persistent, they are not based on facts. Most myths about consumer products have been debunked in the past. As said, these colors do not, in any way, relate to what is in the toothpaste.

The codes are known as color marks or eye marks. In the manufacturing process, these codes are used to show where the package should be folded. In continuous processing, the marks help the high-speed machine spot the right interlocking packages as they speed through the machine.

The codes also contain information about the brand name, logo, and information on product ingredients to be put on the correct sides of the packaging.

The codes contain individual instruction that is can only be picked with light beam sensors.  Information about the ingredients used in the manufacturing of the toothpaste is clearly written on the packaging and on the tube of the toothpaste.

An easier way to debunk this myth is the simple fact that there are far more colors on the toothpaste tube that those primarily used on graphs and memes to show what each color means.

From the video, there is an arm that looks like a circular white arrowhead. It rotates the tube until a sensor can detect that the tube is in the right location. It is only then that the tubes are filled and properly sealed.

It is the information contained in the colored code that allows the machine to stamp, shut, and seal each toothpaste tube precisely the same way for all of the tubes.
