While relatively small quantities of water appear to be colorless, pure water has a slight blue color that becomes deeper as the thickness of the observed sample increases. The hue of water is an intrinsic property and is caused by selective absorption and scattering of blue light.
We usually think of water as a colourless liquid, but it's not true. When white light is shone through a long column of the stuff, the liquid is faintly blueish. That's because the water mops up the longer, redder wavelengths of light, leaving the bluer wavelengths unscathed.
The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water.
In small quantities water appears colorless, but water actually has an intrinsic blue color caused by the slight absorption of light at red wavelengths. For larger bodies of water—ponds, rivers, lakes, and oceans—water appears blue on clear days because it mirrors the blueness of the sky.
True. Pure water looks bluish in color. this statement is true. because the blue color is not absorbed by visible light.
True color is measured after a sample of water has been collected and purified (either by centrifuging or filtration). Pure water tends to look cyan in color and a sample can be compared to pure water with a predetermined color standard or comparing the results of a spectrophotometer.
Water naturally has a blue hue or color. The degree of blue is dependent upon the water's physical and chemical characteristics. The amount of dissolved oxygen, for instance, can influence water's physical characteristics while copper compounds can affect water's chemical characteristics.

Colorless water is considered pure though it may be unsafe for human health. Generally, 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.
But the sun itself is actually white. The sun is white when viewed from space and the sun is white when viewed from earth's surface (except for brief moments around sunrise and sunset). Even when viewed from earth's surface, the sun is almost never yellow.
First of all, as NASA oceanographer Gene Carl Feldman points out, "The water of the ocean is not blue, it's clear. The color of the ocean surface for the most part is based on depth, what's in it and what's below it." So, while the water in the ocean may appear blue, it is in fact, not blue but clear.
Much of the ocean appears blue to our eye, whereas the true color may contain a mix of subtler wavelengths, from blue to green and even red. Cael carried out a statistical analysis using all seven ocean colors measured by the satellite from 2002 to 2022 together.
Because a mirror is designed to reflect all wavelengths on the visible spectrum, a perfect mirror would be white — the reflection of all colors.

Short answer: Mostly blue, with some green, brown and white. Long answer: There are several main colours of the planet Earth, the dominant colour being blue. This comes from the oceans and the atmosphere.
There's no need to build up the suspense: Blood is red. It might vary from a bright cherry red to a dark brick red, but it's always red.
While water does reflect blue-green light, noticeable in great depths, it should appear colorless as used in the home. Ideally, water from the tap is not blue or blue-green. If such is the case, there are certain foreign substances in the water.
The colder part of a diffusion (incomplete combustion) flame will be red, transitioning to orange, yellow, and white as the temperature increases as evidenced by changes in the black-body radiation spectrum. For a given flame's region, the closer to white on this scale, the hotter that section of the flame is.
The moon's actual color is an off-white brown-gray when its dusty surface is sunlit. But Earth's atmosphere modifies our views of the moon, altering colors and shape. Italian photographer Marcella Giulia Pace, who has captured lunar variations for 10 years, chose 48 of her images to compare in this spiral montage.
Pure Water Has a Blue Tint
Bottled water, faucet water, and natural bodies of water contain minerals and sediment, which often change the overall color of water. However, pure water, or water without any other elements, is not completely colorless.
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.
The sky appears blue to the human eye as the short waves of blue light are scattered more than the other colours in the spectrum, making the blue light more visible. To understand why the sky is blue, we first need to understand a little bit about light.
The blue colour indicates that there are quite high levels of copper in the water. The problem normally only occurs where there is relatively new copper plumbing. The blue colour will disappear when the tap is run. If the colour persists then you should contact your water supplier, who can investigate.
Technically, the short wavelengths that scatter across the sky correspond to the colours blue and violet, making the real colour of the sky a bluish purple. However, the cone cells in our eyes that detect colour aren't very sensitive to violet, so we see the sky as blue.
Saturn is very large and is the second largest planet in the Solar System. However, it is made up mostly of gas and is less dense than water. Since it is lighter than water, it can float on water. None of the other planets in our Solar System can do this because they have a higher density than water.
