Water absorbs the red spectrum and transmits the blue. The tungsten filaments in the underwater lamps also emit light that is stronger near the blue end of the spectrum.

It is "blue" because water, H2O, as a molecule is sensitive to that spectrum of the light-waves. That is also why the lakes and oceans and such are also "blue", because the water molecule is sensitive that light-wave...that is, it "reflects" that light-wave. It's much like our sky above our heads...above us at the zenith, the sky appears "blue"...but when the Sun...which is the "source" of light-waves...when it is either rising or setting, turns the sky near the horizons "orange" rather than blue...because the light-wave is, from where you are standing, entering our atmosphere at a diffent "angle" which bends the light and therefore "reflects" a different light-wave. I hope this answer helps.

Why do clouds turn blue in an evening storm? It's a refraction of light. Blue is the highest wavelenght of light and it trales much easier in water. The other wavelenghts are there, just not as bright.The water's also not perfectly clear. There are chemicals and algae in there.

Because Water Is Blue...

Light waves in the violet range tend to escape water easier than other colors due to the refractive properties of the air/water interface.

two reasons wavelenths, reds and such are filtered out as said in upper answer, and also chlorine will allow the water to filter better so in a pool it is more blue in shallower areas than in ponds.

Chlorine makes the water a blueish color for one thing. Also larger bodies of water reflect the color of the sky (blue).

Water tends to filter out longer wavelengths of light (reds), so it looks blue.

its the color of the water.
