Red Sea See?

Where does the name “Red Sea” come from? It’s the red coral that is there. And why is the coral red. Interesting, because red light and color fades the deeper you go down. So why then is the coral red? And do fish see red color? Is it a matter of survival and adaptation? It is an easy yes, But why?

Ok ok, yellow? Don’t know either. But the colors are striking. Yup, distinctive! Not enough to call it the Yellow Sea.
