What do the colors at the bottom of toothpaste tubes mean?!

Some people claim that these colors provide information about the ingredients of toothpaste. For example, they believe that green marks indicate natural ingredients, while black marks mean the toothpaste is made entirely of chemical substances.

However, this belief is incorrect. The colored marks at the bottom of toothpaste tubes are technical indicators used in the manufacturing process.

They help with automated cutting, packaging, and sealing operations during production.

These colors are not related to the ingredients or quality of the toothpaste.
