The light reflecting off the fabric of the shirt combined with the blue bye used to decorate it makes the shirt appear blue to the eye.
Blue is hot yellow is not
Blue!
In general open expanses of water reflect whatever colour is predominant in the environment. This usually tends to be the sky colour. If the sky is clear, water in the sea or lakes will appear blue. If the sky is dull, so also will be the water surface. The tap water in the glass will still usually be clear.
black
It's because the water is deeper.
Reflects blue light, absorbs red.
Some clams appear to have blue lips but in reality, they don't. The lips appear to be blue due to the reflection of their lips in the water.
Water appears varying shades of blue depending on its depth. Deeper pools of water will appear a darker shade of blue, due to scattering of white light and selective absorption. Lesser, shallower amounts of water will appear clear due to the way the light scatters as well.
The Great Blue Heron are abundent in Boise Idaho. Boise is less than 100 miles from Oregon. I am sure that there are large volumes of Blue heron in Oregon.
Because animals pee in it and animals pee is obviously blue ;D
Earth is known as the blue planet because its surface is 75% water, which happens to appear blue.
Because seawater is almost completely transparent, but does have a color. When you put a small quantity in your hand (or in a cup), it will seem transparent, but in large bodies of water it definitely has a color. That's why a sea as a whole appears green, but a handful of sea water doesn't.
The sky is blue because of Rayleigh scattering -- blue photons scatter off air molecules to a large extent, while the other colors travel directly in straight lines from the sun, making the sky appear blue and the sun appear yellow (white minus blue). In space, or on the airless moon, the sky is black and sun is white. It is NOT true that oceans look blue due to sky reflection. Water also scatters blue light, so the explanation of its color is largely the same as that for the sky.
There are several reasons - the first has to do with the reflection of sunlight. Blue wavelengths of light bend more easily, and are reflected off the surface of the water, thus making it appear blue. The water also reflects the color of the sky, so that on cloudy days, it seems more gray than blue. The amount of suspended matter in the water also plays a role, as does the position of the observer.
The water looks colorless when in small quantities but it has actually a very slight blue hue to it. This can be tested with a glass of water and a filled bathtub: the former will appear colorless while the latter will be faint blue.
Because it is blue
