Scientists discover world's oldest colour – bright pink. Pigments found in 1.1bn-year-old rocks beneath the Sahara desert shed light on ‘major puzzle’ about early life.
The colours were discovered by a Phd student, Nur Gueneli, who had crushed the rocks to a powder. She then extracted and analysed molecules of ancient organisms from the substance.
Gueneli said the pigments were more than half a billion years older than previous discoveries.
“The bright pink pigments are the molecular fossils of chlorophyll that were produced by ancient photosynthetic organisms inhabiting an ancient ocean that has long since vanished,” she said in a statement.
