What color is water?

water is white, the thing which makes it green or dark blue are the alga's and the deepness of it, the deeper the water is, so darker is it because it does swallow the light....

> water is white

White like snow? I think you meant "colorless transparent."  Don't make up fake explanations, instead try clicking on the several physics links over to the right. Water is a blue-colored chemical, as shown in measured absorption spectra.

The color of pure water is weak, so in order to see it, you need a water layer several meters thick with a white background below it.

The colour of water is white, because when you go to the beach, the sea looks blue but thats only because its reflecting off the sky. When you pour a glass of water, it looks white and thats what the normal colour is because it isn't relecting off anything, which is why it shows its natural colour= white.

> reflecting off the sky

Notice that the sky in this video is overcast gray. Yet the water behind the ship is not gray, but instead has many blue and blue-green colors.

For an explanation, click on any of the physics/chemistry websites listed to the right.

That aye true

thats awesome..

infrared is indeed not a form of heat, but heat generates infrared radiation.

> heat generates infrared radiation

Not exactly true, since hot objects radiate EM waves, not strictly infrared waves. See Dr. Craig Bohren's book for a good rant about this common physics misconception and the damage it does to students' thinking. Tom Edison made millions because heat generates visible light. Very cold objects mostly radiate in the microwave spectrum. Halogen lamp filaments put out visible and UV. A-bombs put out x-rays. It depends on the temperature of the object.

> they were reflecting the sky

That's the misconception.

In fact, the reflections on waves are sky blue, but between the reflections is the color of water. With muddy rivers the reflections are also sky-blue, but between the reflections is brown water.

Just think of a red car under a blue sky. The reflections are bright blue. But the car is still red. With blue oceans it's more confusing, since you have to distinguish the light blue reflections from the darker blue water.

> Is it just me?

I remember learning some misconceptions. Infrared is a form of heat (no it's not.) The rainbow contains all colors (no, it contains all visible wavelengths, but magenta and cyan are colors, so is brown, so is white.)

In undergrad physics we learn that color is mostly psychological, while wavelength is physics.
