Why doesn't water has its own color?

The molecules of water are made up of oxygen and hydrogen, which cannot absorb a large amount of energy. Therefore, whenever visible light passes through water, it cannot absorb a lot of energy. The difference between the two quantum states of water is extremely small, which results in the generation of complementary colors.

When the amount of water is less, it looks colorless and clear water appears slightly blue, but when the level of water increases in quantity then it appears dark blue. The primary reason for water to appear blue is its absorption properties. Apart from this, the scattering of white light also makes the color of water appear blue to our eyes. However, when the water becomes dirty, its color changes.

The color of seawater also appears blue.

Water has no color but because of sunlight, the seawater appears blue to our eyes. The sea absorbs the violet, indigo, green, yellow, orange and red colors present in the sun's rays, but because of the small wavelength of blue color, the color of seawater changes making it appear blue.
