International researchers have badyzed cyanobacterial pigments extracted from rocks in the Sahara Desert in Africa, dating back 1.1 billion years. The color of the chlorophyll that they have inside is bright pink.
In the geological register of the Earth, the oldest color is bright pink.

From a few rocks obtained in the Sahara Desert in Africa, a team of international researchers has extracted ancient and microscopic cyanobacteria. The experts badyzed the pigments that could identify them, pigments composed internally by chlorophyll dating back about 1100 million years ago. The result of his badysis revealed new conclusions on the subject: the bright pink is the oldest color found in the Earth's geological record.
According to research author Nur Guenell, of the Australian National University, "Bright pink pigments are molecular fossils of chlorophyll that were produced by an ancient photosynthetic organism that lived in an ancient Ocean long gone, "explained the expert from National Geographic.
This badysis, published in the Proceedings of the National Academy of Sciences, showed that these fossils of small cyanobacteria formed the basis of the food chain in the oceans a billion years ago. At that time, animals did not inhabit these ecosystems.
Another researcher, Professor Jochen Brocks, explained for the same portal that larger organisms appear later because of the limited size of their food. An example of this is the appearance of algae, which although they are microscopic, exceed in size, (a thousand times larger than cyanobacteria), warned the scientist.
