The color of a water sample can be reported as: Apparent color is the color of a body of water being reflected from the surface of the water, and consists of color from both dissolved and suspended components. Apparent color may also be changed by variations in sky color or the reflection of nearby vegetation.
Ocean color data is a key tool for research into how marine ecosystems respond to climate change and anthropogenic perturbations. [29] One of the biggest challenges for ocean color remote sensing is atmospheric correction, or removing the color signal of the atmospheric haze and clouds to focus on the color signal of the ocean water.

Anthocyanin pigments are assembled like all other flavonoids from two different streams of chemical raw materials in the cell: One stream involves the shikimate pathway to produce the amino acid phenylalanine, (see phenylpropanoids) The other stream produces three molecules of malonyl-CoA, a C 3 unit from a C 2 unit , [58]
The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .
The background was removed from all photos and each photo was run through the K-means algorithm to get the dominant color. K-means works by dividing the colors of a bird into distinct groups, or ...
However, water and ice absorb in infrared and close the infrared atmospheric window, thereby contributing to the greenhouse effect. The absorption spectrum of pure water is used in numerous applications, including light scattering and absorption by ice crystals and cloud water droplets , theories of the rainbow , determination of the single ...
Leaves change color in the fall because their chromophores (chlorophyll molecules) break down and stop absorbing red and blue light. [1] A chromophore is a molecule which absorbs light at a particular wavelength and reflects color as a result. Chromophores are commonly referred to as colored molecules for this reason.
How light acts in water is critical to how ecosystems function underwater. Knowledge of ocean optics is needed in aquatic remote sensing research in order to understand what information can be extracted from the color of the water as it appears from satellite sensors in space. The color of the water as seen by satellites is known as ocean color ...
