What color were the first ocean?

Scientists discovered ancient oceans were rosy hue, making pink the world’s oldest-known color. Researchers found the mighty little pink pigment in bacterial fossils from the Sahara Desert in Mauritania, West Africa.

Just a thought, I have read some of your articles about pink sea. So maybe we can normalize the idea of having it since it was the first color. The red tide maybe is just a myth? That makes people scarred to swim.

Red tide is true, it is not a myth. As the colors are caused by corals that were intoxicated. Thus, making it dangerous to swim over. I will write more of aquatic plants and about red tide later on. Thank you for asking.

I keep on reading those facts and articles. I will wait for that write up
