ABSTRACT: Chlorophyll is the most widely distributed natural pigment and occurs in the leaves and other parts of almost all plants. Its function in the role of photosynthesis is universally known and yet its natural biosynthesis, action, and ultimate fate in a senescent plant are still not fully...
Colorant Pigment In subject area: Engineering Integral concrete coloring consists of adding powder or liquid colorant (pigment) to cast-in-place and precast concrete, resulting in a uniform color tone throughout the freshly poured slab. From: Journal of Traffic and Transportation Engineering (English...
During the past several years the symmetric three-band (460-, 490-, 520-nm) spectral curvature algorithm (SCA) has demonstrated rather accurate determination of chlorophyll pigment concentration using low-altitude airborne ocean color data. It is shown herein that the in-water asymmetric SCA, when...
The thalli of red (two types, Ⅰ and Ⅱ), orange, green, yellow and wild types of Porphyra yezoensis UEDA and green type of P. tenera KJELLMAN were simultaneously cultured in the Ariake Sea for the same period, and were analyzed for photosynthetic pigments. Chlorophyll a, carotenoids, phyco...
Influence of Pigment Composition on Skin Color in a Wide Range of Fruit and Vegetables The color of fruits and vegetables results from the presence of chlorophyll, carotenoid, and anthocyanin pigments. Instrumental measurements of color are u... JE Lancaster,CE Lister,PF Reay,... - 《J.amer....

The team of researchers discovered bright pink pigment in rocks taken from deep beneath the Sahara in Africa. The pigment was dated at 1.1 billion years old, making it the oldest color on geological record. "The bright pink pigments are the molecular fossils of chlorophyll that were produced by...
Why_Do_Leaves_Change_Color_in_the_Fall
Most plants are green due to chlorophyll(叶绿素). Other colors are caused by structure, like many greens, blues, and whites. Blue bird’s feathers actually contain black pigment, but their structure causes them to appear blue. The scattering of light by tiny dust particles in the air, ...
Remote-sensed ocean color provides measurements of chlorophyll—the phytoplankton pigment that undergoes photosynthesis and is a proxy to marine phytoplankton31. The ocean color fields as measured by SeaWiFS (1997–2010), MODIS (2002–), MERIS (2002–2012), VIIRS (2011–) sensors span different ...
