Water has no color claim is false

Looking at water, you might think that it's the most simple thing around. Pure water is practically colorless, odorless, and tasteless. But it's not at all simple and plain and it is vital for all life on Earth.

colored water imparts adverse effect on human health and aquatic environment. As pure · water doesn’t possess any kind of color, a waters color may provide evidence that there · is some form of contamination.

The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see.

Viewed from the side, the water likely looked clear and colorless. But viewed from above, you probably did see color—green or blue for tap water, and possibly yellow or brown for natural samples. Many people are surprised to find “clear” water looking blue-green. The blue-green color that appears and strengthens with increasing depth arises from an intrinsic property of water—its tendency to absorb light at the red end of the visible spectrum. White light is made up of all different colors of light.

true absorption of pure water is likely to be somewhat lower, at least at violet · and blue wavelengths (Sogandares, et al., 1991). Smith and Baker pointed out · that there are uncertainties because Kd, an apparent optical property, is

The optical properties of pure water are basic input data for many geophysical investigations such as remote sensing of surface water and underwater radiative transfer calculations. Knowledge of the spectral properties of components in surface water is required for accurate interpretation of ...

The blue hue is created by water itself. Sunlight contains the full spectrum of visible colors, from red to violet and the whole rainbow in between. Different colors of light have different wavelengths.

The color of water varies with the ambient conditions in which that water is present. While relatively small quantities of water appear to be colorless and transparent, pure water has a slight blue color that becomes deeper as the thickness of the observed sample increases.
