World’s Oldest Color May Surprise You

Everyone who knows me know my favorite color is purple, but do you know what the world’s oldest color is? It may surprise you.

Could it be the color of the sun? A yellow that looks like mustard or something bright. Or is it a color that looks like the deepest green from the forest or the green hues in Ireland? Maybe it’s the color of the clear blue sky. Well, scientists have finally figured out what’s the oldest color in the world? Any guesses? It’s the color…Pink.

The color of bubble gum, flamingos, cotton candy, and Pepto….bright pink.

Researchers discovered the ancient pink pigments in 1.1-billion-year-old rocks deep beneath the Sahara Desert in the Taoudeni Basin of Mauritania, West Africa, making them the oldest colors in the geological record.

Dr. Nur Gueneli, who discovered the pigments as part of her PhD studies at Australia National University, said that the bright pink colors are more than 500 million years older than the next oldest known pigments and were produced by ancient ocean organisms. Gueneli also stated, “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.”

But what did they do to figure out that pink is the oldest color? Researchers crushed billion-year-old rocks into powder, and extracted and analyzed the molecules of ancient organisms within them.

I’m a little surprised at this discovery, I would’ve thought the oldest color would’ve been maybe red, green, brown, or even blue…but never bright pink. What did you think the oldest color in the world was?
