Copper Sun Book Essay
All the colors you see on your computer screen are made by mixing them in different intensities. Light which triggers this greenness response more than the yellowness or blueness of the other color opponent mechanism is called green.
In some cases, one is missing or faulty, which can cause color blindnessincluding the common inability to distinguish red and yellow from green, known as deuteranopia or red—green color blindness.
Studies show that a green environment can reduce fatigue. On the HSV color wheelalso known as the RGB color wheelthe complement of green is magenta ; that is, a color corresponding to an equal mixture of red and blue light one of the purples.
On a traditional color wheel, based on subtractive color, the complementary color to green is considered to be red. A unique green green appearing neither yellowish nor bluish is produced on such a device by mixing light from the green primary with some light from the blue primary.
Lasers Lasers emitting in the green part of the spectrum are widely available to the general public in a wide range of output powers. The most common green lasers use diode pumped solid state DPSS Copper sun aoi to create the green light.
YVO4 or neodymium-doped yttrium aluminium garnet Nd: YAG and induces it to emit This deeper infrared light is then passed through another crystal containing potassium, titanium and phosphorus KTPwhose non-linear properties generate light at a frequency that is twice that of the incident beam Green lasers have a wide variety of applications, including pointing, illumination, surgery, laser light showsspectroscopyinterferometryfluorescenceholographymachine visionnon-lethal weapons and bird control.
Pigments, food coloring and fireworks The Chicago River is dyed green every year to mark St. Patrick's Day Many minerals provide pigments which have been used in green paints and dyes over the centuries.
Pigments, in this case, are minerals which reflect the color green, rather that emitting it through luminescent or phosphorescent qualities.
The large number of green pigments makes it impossible to mention them all. Among the more notable green minerals, however is the emeraldwhich is colored green by trace amounts of chromium and sometimes vanadium. Widely thought to have been due to copper because copper compounds often have blue and green colors, the blue-green color is likely to be derived from small quantities of lead and water in the feldspar.
The process of making verdigris was described in ancient times by Pliny. It was used by the Romans in the murals of Pompeii, and in Celtic medieval manuscripts as early as the 5th century AD. It produced a blue-green which no other pigment could imitate, but it had drawbacks; it was unstable, it could not resist dampness, it did not mix well with other colors, it could ruin other colors with which it came into contact.
Leonardo da Vinciin his treatise on painting, warned artists not to use it. It was widely used in miniature paintings in Europe and Persia in the 16th and 17th centuries.
Its use largely ended in the late 19th century, when it was replaced by the safer and more stable chrome green. It became popular with painters, since, unlike other synthetic greens, it was stable and not toxic.
Vincent van Gogh used it, along with Prussian blueto create a dark blue sky with a greenish tint in his painting Cafe terrace at night.
It is composed of clay colored by iron oxidemagnesiumaluminum silicateor potassium. The clay was crushed, washed to remove impurities, then powdered. It was sometimes called Green of Verona. Sven Rinmana Swedish chemist, discovered this compound in Central Texas Electronics Association.

Copper is the source of the green color in malachite pigments, chemically known as basic copper(II) carbonate.
 Verdigris is made by placing a plate or blade of copper, brass or bronze, slightly warmed, into a vat of fermenting wine, leaving it there for several weeks, and then scraping off and drying the green powder that forms on the metal.
