Green Blue Slate

Slate turkey

The Slate, or Blue Slate, is a breed of domestic turkey known for the slate gray color of its plumage. Lighter birds are sometimes called Lavender turkeys. Turkeys of the Slate breed may actually be any number of shades between pure black and white, but only ash-gray birds are eligible for showing under the directive of the American Poultry Association’s ‘’Standard of Perfection’’, into which they admitted as a variety in 1874. Slate turkeys are listed as critically endangered by the American Livestock Breeds Conservancy, and meet the definition of a heritage turkey breed.

Blue-green

Blue-green is the color between blue and green. It belongs to the cyan family.

Slate

Slate is a fine-grained, foliated, homogeneous, metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade, regional metamorphism. It is the finest-grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression.

Green

Green is the color between cyan and yellow on the visible spectrum. It has 295–350 different shades. It is evoked by light which has a dominant wavelength of roughly 495–570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content.
