Light scattering by suspended matter is required in order that the blue light produced by water's absorption can return to the surface and be observed. Such scattering can also shift the spectrum of the emerging photons toward the green, a color often seen when water laden with suspended particles is observed. [citation needed]
Red light is most easily absorbed and thus does not reach great depths, usually to less than 50 meters (164 ft). Blue light, in comparison, can penetrate up to 200 meters (656 ft). [3] Second, water molecules and very tiny particles in ocean water preferentially scatter blue light more than light of other colors. Blue light scattering by water ...
Water vapor concentration for this gas mixture is 0.4%. Water vapor is a greenhouse gas in the Earth's atmosphere, responsible for 70% of the known absorption of incoming sunlight, particularly in the infrared region, and about 60% of the atmospheric absorption of thermal radiation by the Earth known as the greenhouse effect.

The color light blue is commonly regarded as calming and relaxing. Because of this, it is sometimes used to paint hospital rooms. Since the color light blue reminds many people of water, light blue is a popular color for painting bathrooms or for porcelain bathroom fixtures. School colors
In other words, as light passes through a greater distance of water color is selectively absorbed by the water. Color absorption is also affected by turbidity of the water and dissolved material. Water preferentially absorbs red light, and to a lesser extent, yellow, green and violet light, so the color that is least absorbed by water is blue ...
Pure water is visibly blue due to absorption of light in the region c. 600–800 nm. [89] The color can be easily observed in a glass of tap-water placed against a pure white background, in daylight. The principal absorption bands responsible for the color are overtones of the O–H stretching vibrations.
Milky sea effect off the coast of Somalia in the Indian Ocean. Milky seas (Somali: Kaluunka iftiima; English: Milky seas), sometimes confused with mareel, are a luminous phenomenon in the ocean in which large areas of seawater (up to 100,000 km 2 or 39,000 sq mi [1]) appear to glow diffusely and continuously (in varying shades of blue).
Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. [26] Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color.
