The correct answer to this question is Blue. There are five oceans in the world, which are the Arctic, Atlantic, Pacific, Indian, and Southern Oceans. They are all in different locations, but one common trait they share is that they are all the color blue. Indian, Arctic, and Southern are all lighter shades of blue, while the Atlantic and Pacific are the darker shades of blue.
The reason why the color of the ocean is blue is because of the light spectrum. The water absorbs the red part, which lets us see the blue part. When one looks down at the ocean, they may also see other colors like red or green, because the light is bouncing off the particles and sediments in the water.
