In olden times sailors used to refer to the four cardinal points of the Earth in terms of colours. One of the cardinal points, South, was assigned the colour red, and the sea that lies South, between Africa and Asia connected to the Indian Ocean, was called the Red Sea. In English language there are four seas that are named after colours. They include the Red Sea, the Black Sea, the White Sea and the Yellow Sea.
