The discussion centers on the natural colors of unpolluted ocean waters, exploring whether these colors are merely reflections of the sky. While sky reflection contributes to the perceived color—blue on clear days and gray on cloudy ones—it's not the sole factor. The absorption of light by water plays a significant role, with water absorbing more red light, which affects the color seen. Additionally, variations in color occur due to environmental factors, such as brown hues near estuaries, blue-green shades in shallow sandy areas, and red during algae blooms.
