The four colored seas in the world are?

The four colored seas in the world are the Red Sea, White Sea, Black Sea, and Yellow Sea. Their names are unusual because most bodies of water described as seas appear blue or blue-green from the surface.

The Red Sea lies between northeastern Africa and the Arabian Peninsula, while the Black Sea sits between southeastern Europe and western Asia. The White Sea is a southern inlet of the Barents Sea on Russia's northwest coast, and the Yellow Sea lies between mainland China and the Korean Peninsula.

The names have different proposed origins. The Yellow Sea receives large amounts of yellow-brown sediment from the Yellow River. The White Sea is heavily affected by seasonal ice. For the Black and Red seas, historical color symbolism linked black with the north and red with the south in some regional naming traditions, although the exact origins are debated.

These are seas whose English names contain color words, not seas that are permanently colored those shades. The Red Sea can show reddish algae, and the Yellow Sea can look especially muddy, but neither is uniformly red or yellow.
