Yellow
From Wikipedia, the free encyclopedia
Yellow is any color of light that stimulates both the red and green cone cells of the retina, but not the blue cone cells. Light with a wavelength of 565–590 nm is yellow, though light with both red frequencies and green frequencies, such as mixing orange and lime light, or red and green light, is also yellow, and its scientifically defined complementary color in terms of color mixing using light is blue. Of all colors, yellow is the most difficult color for the eye to process.[citation needed]

[edit] Process Yellow (pigment Yellow) (printer's Yellow)(canary Yellow)
Yellow is one of the three subtractive primary colors, along with magenta and cyan. The CMYK system for color printing is based on using four inks, one of which is a Yellow color. This is not in itself a standard color, though a fairly narrow range of Yellow inks are used.
Because of the characteristics of paint pigments and use of different color wheels, painters traditionally regard the complement of Yellow as the color indigo (blue-violet).
The CMYK printing process was invented in the 1890s, when newspapers began to publish color comic strips.
Process Yellow is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure Yellow ink.
This color is also called canary Yellow.

[edit] Plants and animals
- The yellow birch (Betula alleghaniensis) is a birch species native to eastern North America, from Nova Scotia, New Brunswick, and southern Quebec west to Minnesota, and south in the Appalachian Mountains to northern Georgia. They are medium-sized deciduous trees and can reaching about 20 m tall, trunks up to 80 cm in diameter. The bark is smooth and yellow-bronze and the wood is extensively used for flooring, cabinetry, and toothpicks.
- Yellow-breasted Chats (Icteria virens) are large foraging songbird found in southern parts of Canada, the United States, Mexico, and Central America. They are olive with a white bellies and a yellow throat and breast, with a long tail, a thick heavy bill, a large white eye ring, and dark legs.
- A yellow-fever mosquito is a mosquito in the Aedes genus, so named because they transmit dengue fever and yellow fever, the mosquito-born viruses.
- Yellow-green alga, also called xanthophytes, are a class of algae in the Heterokontophyta division. Most live in freshwater, but some are found in marine and soil habitats. They vary from single-celled flagellates to simple colonial and filamentousforms. Unlike other heterokonts, yellow-green algae's chloroplasts do not contain fucoxanthin, which is why they have a lighter color.
- The Yellowhammer (Emberiza citrinella) is a passerine in the bunting family Emberizidae. It breeds across Europe and much of Asia. Most yellowhammers are resident, but some far northern birds migrate south in winter. It is common in all sorts of open areas with some scrub or trees. They are large with a thick seed-eater's bill. The males have a bright yellow head, yellow underparts, and a heavily streaked brown back. Females are much duller and more streaked below.
- Yellowjackets are black-and-yellow wasps of the genus Vespula or Dolichovespula (though some can be black-and-white, the most notable of these being the bald-faced hornet, Dolichovespula maculata). They can be identified by their distinctive black-and-yellow color, small size (slightly larger than a bee), and entirely black antennae.
- Yellow poplar is a common name for Liriodendron, the tuliptree. The name is inaccurate as this genus is not related to poplars.
- The Yellow-shafted Flicker (Colaptes auratus) is a large woodpecker species of eastern North America. They have yellow shafts on their wing and tail feathers.
- Yellowtail is the common name for dozens of different fish species that have yellow tails or a yellow body.
- Goldenrod is a yellow flowering plant in the Family Asteraceae

[1]
