Well, I'll restrict my answer to just your main question... the sky is not blue because it reflects the ocean. The sky is blue because our atmosphere scatters the light we recieve from the sun. That's why when the sun is above us it (the sky) appears blue, and when it's rising or setting, it appears reddish. Technically, the sky isn't blue at all, it is violet. The reason it appears blue is that the human eye can not detect violet in the presence of longer wavelengths.

Aaaaaaaactually. You're wrong. The sky is blue because it contains billions of trillions of tiny water droplets -- what you and I affectionately know as humidity or clouds. These water droplets capture and refract the light from the sun, and blue has one of the shortest wave lengths and can pierce through other water drops, so our eyes pick up on the blue light. The ocean is blue 1-because it reflects the sky and 2-because the same principle above applies to bodies of water, except to a lesser degree.

Technically the sky isn't blue because it reflects the sea. that is blue because of white gentle. all the different shades are absorbed into the sky and the in elementary words colour it truly is contemplated decrease back to oyur eyes is blue. a similar element is actual about the sea.

When the light from the sun is absorbed by the ocean and the waters of the ocean, the prismic colors are divided (ROYGBIV), and red, orange, yellow, and green are absorbed quickly, leaving the water to look like a bluish liquid. This causes the water to adopt a blue color, and the sky to reflect it.

Why is the sky blue?
The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Combined, these effects scatter (bend away in all directions) some short, blue light waves while allowing almost all longer, red light waves to pass straight through. When we look toward a part of the sky not near the sun, the blue color we see is blue light waves scattered down toward us from the white sunlight passing through the air overhead. Near sunrise and sunset, most of the light we see comes in nearly tangent to the Earth's surface, so that the light's path through the atmosphere is so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red.

Scattering and absorption are major causes of the attenuation of radiation by the atmosphere. Scattering varies as a function of the ratio of the particle diameter to the wavelength of the radiation. When this ratio is less than about one-tenth, Rayleigh scattering occurs in which the scattering coefficient varies inversely as the fourth power of the wavelength. At larger values of the ratio of particle diameter to wavelength, the scattering varies in a complex fashion described, for spherical particles, by the Mie theory; at a ratio of the order of 10, the laws of geometric optics begin to apply.

Why is the sky blue instead of violet?
Because of the strong wavelength dependence (inverse fourth power) of light scattering according to Raleigh's Law, one would expect that the sky would appear more violet than blue, the former having a shorter wavelength than the latter. There is a simple physiological explanation for this apparent conundrum. Simply put, the human eye cannot detect violet light in presence of light with longer wavelengths. There is a reason for this. It turns out that the human eye's high resolution color-detection system is made of proteins and chromophores (which together make up photoreceptor cells or "Cone" structures in the eye's fovea) that are sensitive to different wavelengths in the visible spectrum (400 nm–700 nm). In fact, there are three major protein-chromophore sensors that have peak sensitivities to yellowish-green (564 nm), bluish-green (534 nm), and blue-violet (420 nm) light. The brain uses the different responses of these chromophores to interpret the spectrum of the light that reaches the retina.

When one experimentally plots the sensitivity curves for the three color sensors (identified here as long (L), middle (M), and short (S) wavelength), three roughly "bell-curve" distributions are seen to overlap one another and cover the visible spectrum. We depend on this overlap for color sensing to detect the entire spectrum of visible light. For example, monochromatic violet light at 400 nm mostly stimulates the S receptors, but also slightly stimulates the L and M receptors, with the L receptor having the stronger response. This combination of stimuli is interpreted by the brain as violet. Monochromatic blue light, on the other hand, stimulates the M receptor more than the L receptor. Skylight is not monochromatic; it contains a mixture of light covering much of the spectrum. The combination of strong violet light with weaker blue and even weaker green and yellow strongly stimulates the S receptor, and stimulates the M receptor more than the L receptor. As a result, this mixture of wavelengths is perceived by the brain as blue rather than violet.

Why is the sea blue?
A common misconception concerning the color of water in large bodies, such as the ocean, is that the blue is due to the reflections from the sky on its surface. This is not true, but was believed to be so decades ago. The real reason the ocean is blue is because the water, pure water, is blue. Yes, according to its frequency spectra, water is a very light shade of turquoise blue. But you need a huge amount of it to really see its color. It’s like a teaspoon of oil, it looks transparent on a white spoon, but in the bottle looks yellowish.

If the ocean owed its color to the sky, it would be a lighter shade of blue and it would be white on cloudy days. You can see clouds reflected in the surface on the sea, but they don’t completely change its color. Some constituents of sea water can influence the shade of blue you see in the ocean. This is why it can look greener or bluer in different areas. Swimming pools with white bottom, would have water that look transparent not turquoise blue, as it is observed even in indoor pools, where there’s no sky to be reflected. The scientific explanation involves the theory of radiative transfer (absorption and scattering), and material electromagnetic spectra.

Particular matter
The color of a water sample is caused by both dissolved and particulate material in water, and is measured in Hazen Units (HU). Either of these components can be deeply colored, for instance dissolved organic molecules called tannins can result in dark brown colors, or algae floating in the water ("particles") can impart a green color. But in a lot of cases water is a clear to neutral color due to a lack of pigments in the water. (e.g. the sea)

The color of a water sample can be reported as:

1. Apparent color
2. True color

Apparent color is the color of the whole water sample, and consists of color due to both dissolved and suspended components.

True color is measured by filtering the water sample to remove all suspended material, and measuring the color of the filtered water, which represents color due to dissolved components.

Testing for color can be a quick and easy test which often reflects the amount of organic material in the water (although certain inorganic components like iron or manganese can also impart color).
