Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean, while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. [ 1] This field of study developed alongside water remote ...
The color of water varies with the ambient conditions in which that water is present. 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 ...
Deep sky blue is an azure-cyan color associated with deep sky blue. Deep sky blue is a web color. This color is on the color wheel (RGB/HSV color wheel) halfway between azure and cyan. The traditional name for this color is Capri. [42] The first use of Capri as a color name in English was in 1920. [43]
The deep blue color is caused by the high transparency of water and bright white carbonate sand. Blue light is the most enduring part of the spectrum; other parts of the spectrum—red, yellow, and finally green—are absorbed during their path through water, but blue light manages to reach the white sand and return upon reflection.
Azurite (Cu 3 (CO 3) 2 (OH) 2), with a deep blue colour, was once employed in medieval years, but it is unstable pigment, losing its colour especially under dry conditions. Lapis lazuli, mined in Afghanistan for more than three thousand years, was used for jewelry and ornaments, and later was crushed and powdered and used as a pigment. The more ...
Ultramarine is a deep blue color pigment which was originally made by grinding lapis lazuli into a powder. [ 2] Its lengthy grinding and washing process makes the natural pigment quite valuable—roughly ten times more expensive than the stone it comes from and as expensive as gold. [ 3][ 4] The name ultramarine comes from the Latin ultramarinus.
Most of the ocean is blue in color, but in some places the ocean is blue-green, green, or even yellow to brown. [64] Blue ocean color is a result of several factors. First, water preferentially absorbs red light, which means that blue light remains and is reflected back out of the water.
The Great Blue Hole is a giant marine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 70 km (43 mi) from the mainland and Belize City. The hole is circular in shape, 318 m (1,043 ft) across and 124 m (407 ft) deep. [ 1][ 2] It has a surface area of 70,650 square metres (760,500 sq ft).
