What is the colour of water, and why does it look clear in a glass but blue in the sea

Water's colour, often unseen in small amounts, reveals itself in larger bodies like the sea. Scientists explain that water absorbs red light more than blue, a phenomenon noticeable only with significant depth. Particles, algae, and even sky reflection further influence the hues we perceive, turning clear water into a vibrant spectacle.
