我爱我的祖国60年，光辉岁月弹指挥间，60年，中华大地沧桑巨变。2009年，我们伟大的祖国迎来了她的60岁生日。1949年，中华人民共和国成立了！饱经战争沧桑与落后苦难的中国人民终于重新站起来了！中国像一只巨龙一样，以一个大国的身份重新屹立于世界东方！那时的中国，民生凋敝，经济严重落后，国家事业百废待兴，政府和人民面对一个满目疮痍的中国面孔，并没有畏缩，勇往直前，仅仅用了三年的时间就恢复了国民经济，涌现出一批可歌可泣的感人事迹。经过三年的经济恢复，国民经济得到根本好转，工业生产已经超过历史最高水平，但是我国那时还是一个落后的农业国，许多工业产品的人均拥有量远远低于发达国家。为了有计划地进行社会主义建设，我国政府开始编制发展国民经济的五年计划。第一个五年计划从1953年开始执行，它成为我国工业化的起点。第一个五年计划开始时，我国的工业化水平是极低的。出行用的自行车，人们叫它“洋马”，点火用的火柴，人们叫它“洋火”，钉东西用的钉子，人们叫它“洋钉”。因为那时的中国人没有见过这些新奇的东西，也不会造，都是从西洋传过来的。那个艰苦的年代，我没有经历过，但从我看过的资料片中完全能够体会，当时的中国人民依旧生活在极端贫穷之中。光阴如水，岁月如梭。时光来到了2009年，我正在电视机前，收看着中国第三个南极科考站落成的新闻。又是一个重大成就，我开始浮想联翩，我想起了祖国成功举办了第二十九届夏季奥运会，想起鸟巢，想起了奥运健儿们的英姿，我想起了祖国接连成功发射了神州五号、六号、七号载人航天飞船，想起太空，想起了中国已经成为世界航天领域举足轻重的一员，我想起了改革开放整整三十年里我国人均国内生产总值保持年均10%的增幅，想起中国国力，想起中国已经成为这个世界综合国力第六的国家，想起新中国成立的这一甲子中国的国际地位迅速的、不断地提升，想起新中国历史，想起了新中国成立六十年来光辉的足迹！ 我为我的祖国母亲骄傲，我为成为中国母亲的儿子骄傲！

Primary colors are sets of colors that can be combined to make a useful range of colors. For human applications, three primary colors are usually used, since human color vision is additive combination of colors, as in overlapping projected lights or in CRT displays, the primary colors normally used are red, green, and blue. For subtractive combination of colors, as in mixing of pigments or dyes, such as in printing, the primaries normally used are cyan, magenta, and yellow,[1] though the set of red, yellow, blue is popular among artists.[2] See RGB color model, CMYK color model, and RYB color model for more on these popular sets of primary choice of primary colors is essentially arbitrary; for example, an early color photographic process, autochrome, typically used orange, green, and violet primaries.[3]The most commonly used additive color primaries are the secondary colors of the most commonly used subtractive color primaries, and vice colors are not a fundamental property of light but are often related to the physiological response of the eye to light. Fundamentally, light is a continuous spectrum of the wavelengths that can be detected by the human eye, an infinite-dimensional stimulus space.[4] However, the human eye normally contains only three types of color receptors, called cone cells. Each color receptor responds to different ranges of the color spectrum. Humans and other species with three such types of color receptors are known as trichromats. These species respond to the light stimulus via a three-dimensional sensation, which generally can be modeled as a mixture of three primary colors.[4]Before the nature of colorimetry and visual physiology were well understood, scientists such as Thomas Young, James Clark Maxwell, and Hermann von Helmholtz expressed various opinions about what should be the three primary colors to describe the three primary color sensations of the eye.[5] Young originally proposed red, green, and violet, and Maxwell changed violet to blue; Helmholtz proposed "a slightly purplish red, a vegetation-green, slightly yellowish (wave-length about 5600 tenth-metres), and an ultramarine-blue (about 4820)".[6] In modern understanding, the human cone cells do not correspond to any real primary with different numbers of receptor cell types would have color vision requiring a different number of primaries. For example, for species known as tetrachromats, with four different color receptors, one would use four primary colors. Since humans can only see to 400 nanometers (violet), but tetrachromats can see into the ultraviolet to about 300 nanometers, this fourth primary color might be located in the shorter-wavelength birds and marsupials are tetrachromats, and it has been suggested that some human females are tetrachromats as well[7][8], having an extra variant version of the long-wave (L) cone type.[9] The peak response of human color receptors varies, even among individuals with "normal" color vision[10]; in non-human species this polymorphic variation is even greater, and it may well be adaptive[11]. Most mammals other than primates have only two types of color receptors and are therefore dichromats; to them, there are only two primary would be incorrect to assume that the world "looks tinted" to an animal (or human) with anything other than the human standard of three color receptors. To an animal (or human) born that way, the world would look normal to it, but the animal's ability to detect and discriminate colors would be different from that of a human with normal color vision. If a human and an animal both look at a natural color, they see it as natural; however, if both look at a color reproduced via primary colors, such as on a color television screen, the human may see it as matching the natural color, while the animal does not; in this sense, reproduction of color via primaries must be "tuned" to the color vision system of the that combine emitted lights to create the sensation of a range of colors are using the additive color system. Typically, the primary colors used are red, green, and blue.[12]Television and other computer and video displays are a common example of the use of additive primaries and the RGB color model. The exact colors chosen for the primaries are a technological compromise between the available phosphors (including considerations such as cost and power usage) and the need for large color triangle to allow a large gamut of colors. The ITU-R primaries are 1931 RGB color triangle with monochromatic primariesAdditive mixing of red and green light produces shades of yellow, orange, or brown.[13] Mixing green and blue produces shades of cyan, and mixing red and blue produces shades of purple, including magenta. Mixing nominally equal proportions of the additive primaries results in shades of grey or white; the color space that is generated is called an RGB color CIE 1931 color space defines monochromatic primary colors with wavelengths of nm (violet), nm (green) and 700 nm (red). The corners of the color triangle are therefore on the spectral locus, and the triangle is about as big as it can be. No real display device uses such primaries, as the extreme wavelengths used for violet and red result in a very low luminous article: RYB color modelRYB (red, yellow, and blue) is a historical set of subtractive primary colors. It is primarily used in art and art education, particularly painting.[14] It predates modern scientific color RYB Color WheelRYB make up the primary color triad in a standard color wheel; the secondary colors VOG (violet, orange, and green) make up another triad. Triads are formed by 3 equidistant colors on a particular color wheel; neither RYB nor VOG is equidistant on a perceptually uniform color wheel, but rather have been defined to be equidistant in the RYB wheel.[15]Painters have long used more than three "primary" colors in their palettes—and at one point considered red, yellow, blue, and green to be the four primaries[16]. Red, yellow, blue, and green are still widely considered the four psychological primary colors,[17] though red, yellow, and blue are sometimes listed as the three psychological primaries [18], with black and white occasionally added as a fourth and fifth [19].During the 18th century, as theorists became aware of Isaac Newton’s scientific experiments with light and prisms, red, yellow, and blue became the canonical primary colors—supposedly the fundamental sensory qualities that are blended in the perception of all physical colors and equally in the physical mixture of pigments or dyes. This theory became dogma, despite abundant evidence that red, yellow, and blue primaries cannot mix all other colors, and has survived in color theory to the present day.[20]Using red, yellow, and blue as primaries yields a relatively small gamut, in which, among other problems, colorful greens, cyans, and magentas are impossible to mix, because red, yellow, and blue are not well-spaced around a perceptually uniform color wheel. For this reason, modern three- or four-color printing processes, as well as color photography, use cyan, yellow, and magenta as primaries instead.[21] Most painters include colors in their palettes which cannot be mixed from yellow, red, and blue paints, and thus do not fit within the RYB color model. Some who do use a three-color palette opt for the more evenly spaced cyan, yellow, and magenta used by printers, and others paint with 6 or more colors to widen their gamuts.[22] The cyan, magenta, and yellow used in printing are sometimes known as "process blue," "process red," "process yellow."[23][edit] CMYK color model, or four-color printingMain article: CMYK color modelIn the printing industry, to produce the varying colors the subtractive primaries cyan, magenta, and yellow are applied together in varying amounts. Before the color names cyan and magenta were in common use, these primaries were often known as blue-green and purple, or in some circles as blue and red, respectively, and their exact color has changed over time with access to new pigments and technologies.[24]Subtractive color mixing – the magenta and cyan primaries are sometimes called purple and blue-green, or red and blueMixing yellow and cyan produces green colors; mixing yellow with magenta produces reds, and mixing magenta with cyan produces blues. In theory, mixing equal amounts of all three pigments should produce grey, resulting in black when all three are applied in sufficient density, but in practice they tend to produce muddy brown colors. For this reason, and to save ink and decrease drying times, a fourth pigment, black, is often used in addition to cyan, magenta, and resulting model is the so-called CMYK color model. The abbreviation stands for cyan, magenta, yellow, and key—black is referred to as the key color, a shorthand for the key printing plate that impressed the artistic detail of an image, usually in black ink.[25]In practice, colorant mixtures in actual materials such as paint tend to be more complex. Brighter or more saturated colors can be created using natural pigments instead of mixing, and natural properties of pigments can interfere with the mixing. For example, mixing magenta and green in acrylic creates a dark cyan—something which would not happen if the mixing process were perfectly the subtractive model, adding white to a color, whether by using less colorant or by mixing in a reflective white pigment such as zinc oxide, does not change the color’s hue but does reduce its saturation. Subtractive color printing works best when the surface or paper is white, or close to system of subtractive color does not have a simple chromaticity gamut analogous to the RGB color triangle, but a gamut that must be described in three dimensions. There are many ways to visualize such models, using various 2D chromaticity spaces or in 3D color spacesNotes and references^ Matthew Luckiesh (1915). Color and Its Applications. D.
