1、色彩基礎(chǔ)知識( Basic knowledge of color ) The basic knowledge of color.Txt52, everyone is a parabola, talent determines its opening, and the highest point requires the efforts of the day after tomorrow. No autumn leaves fall, where spring green shoots hungry bright? Only know how to lose, will have again.

2、The color in the web page is the most intuitive understanding of the website, and it is also a major component of the website's unified style design. Many web sites, let you remember the 32 sites, the most profound is the website that color, including the inside of the color series, color matchi

3、ng elements, the overall color atmosphere etc.For example, in the film "hero" in the process, remember the director Zhang Yimou said the words: "after a few years, say" hero ", you will remember those colors, for example, you will remember there are two red woman dancing in

4、the sky in yellow, you will remember in as the blue Lake, there are two menin the martial arts exchange, on the surface like a bird, like a dragonfly." This is the color of the human eye the most direct stimulation of the embodiment.In this paper, the knowledge is not to grasp the basic knowled

5、ge of color sanyuanshai, because they have to learn in school, here the introduction of relevant knowledge, but according to the needs of the site design, develop a web color scheme and analysis ability, cultivate a sense of color on the web.First, the basic knowledge of colorThe color of the monito

6、r belongs to the light source color. Inside the display screen are evenly distributed red (RED),green (GREEN), blue (BLUE) fluorescent particles, when connected to the display power supply, the monitor glows and displays different colors. The color of the display is displayed by mixing the three pri

7、mary colors of the light source. According to the different connotations of the three colors, the display can display up to 16 million colors.That is to say all the colors in the display by the red (RED), green (GREEN), blue (BLUE) mixing the colors to display, display the color display modecalled R

8、GBcolor or color space. In everyday life, we don't talk too much about the concept of RGBcolor system, but because web designers need to use the RGB color model, it's important to point out.Regardless of any color, all have three important properties: color, lightness, chroma, commonly known

9、 as the three elements of the three properties of color or color.1, color name(Hue): color name(Hue, referred to as "H" or "hue") is the name of the color distinction, that is, the name of the color, such as the name of a person in general, used to distinguish between different p

10、eople.2, brightness (Value): lightness (Value, referred to as V) when light is strong, the feeling is bright, the light isweak, thefeeling is quite dark, and the intensity of the color is the so-called lightness, high brightness refers to the color is bright, and the relative brightness is low, colo

11、r is dark.3, chroma (Chroma): chroma (Chroma, referred to as C) refers to the color purity, usually with a color with the color of the color of the proportion, to distinguish the saturation level, a high proportion of solid to solid ratio of low to high chroma, low chroma, color in the situation, we

12、 are usually very easy to feel high chroma, but sometimes it is not easy to make a correct judgment, because the vulnerable to lightness effect, such as everyone is most easily misunderstood, black and white ash is no chroma, they only brightness.Traditional color ring RGB color ring4, color ring: e

13、ach color pattern contains a set of three primary colors, and then through this group of three primary colors of each other mixed to produce different colors. In traditional colors, three colors refer to blue, red, and yellow. In RGB color patterns, the primary colors of light are red, green, and bl

14、ue. Any combination of two colors will produce a color group. The three color is a mixture of primary and secondary colors, or is produced by mixing two primary colors. Weuse color rings to represent the logic of color. You can see from the diagram below that the color ring of RGB is very different

15、from the color ring used by traditional artists.Color rings show the relationship between colors that can be used to achieve contrast and balance. The color ring contains fully saturated colors and someless white, gray or black colors that can be rendered, tonal, and shaded. And compared to pure col

16、or mixing can generate dynamic color harmony; and the use of color - that is similar to the brightness value of unsaturated colors and dark degree almost - can be designed more detailed, more supple harmonic colors.Two, the way to deal with colorIn theory, there are two methods: 1, color processing

17、additive, mixing of different colors to form white light; 2, subtractive, use of pigment to reduce light. CMYK system used in the traditional artist color plate and print are subtractive mode. On the website,What we are facing is the projection of light rather than the reflection of light from the o

18、bject, so the additive pattern is used, that is, the RGB mentioned above.1, plus color methodIn nature, the light waves we see are reflected through objects into our retinas, but not only in color. Stage lighting, for example, uses white light to pass through colored filters to produce different col

19、ored lights. Computer screens are also used to project light waves, but the difference is that they produce light by projecting light from an electronic light gun and projecting onto a phosphor screen. These electronic guns emit three colors: red, green, and blue. With these three colors, the comput

20、er screen produces a complete spectrum.In the RGB system, we can also make a spectrum by mixing the three primary colors. Mixing any two colors, will produce three times primary colors: green, magenta, yellow. As mentioned earlier, you can makea white light by adding the three primary colors of ligh

21、t together. So, if a RGB value is 255255255, it is white, and the sixteen decimal notation is (FFFFFF). If the light of the third color (RGB:0,0,0) is completely removed,black is produced, and the sixteen decimal notation is (000000). And we often see in the web Code "bgColor=#FFFFFF" refe

22、rs to the background color is white.2, the subtractive methodThe opposite pattern of the RGB pattern is the CMYK pattern, which is the use of light waves to produce colors. Since the object's color comes from reflected light waves, the system uses primary colors to absorb red, green, or blue lig

23、ht from objects. For example, if you reduce red light, excess green waves and blue waves produce cyan. Pigments used to remove red light and reflect green and blue light show cyan. The sameprint can be used to absorb part of the magenta and blue green, yellow light is absorbed to use part of the.In

24、this way, we can clearly see that the primary colors used in the CYMKmodel are the second colors in the RGBpattern, and vice versa. Furthermore, if the red, green and blue mix together to form white light, then that will be green, magenta, yellow pigment mixed color producing black together will, be

25、cause the light colors will be absorbed by the pigment. However, limited by the factors of paint and printing system, mixed green, magenta, yellow and can not fully absorb all the light.Therefore, you have to add a black color to complete it, so you have the K element inside the CMYK.3, color manage

26、mentWith these two different ways of reproducing colors, it would be a bit of a challenge to create both digital and printed images at the same time. In addition to correspondence between additive and subtractive difficulties, RGBand CMYKcan use the color range difference is quite large. Therefore,

27、for sometimes we need to do cross media, we have a set of color management system which can be used to do color conversion according to the output device, which can alleviate a lot of headaches. Color management systems can be included in operating systems and certain applications, such as Photoshop

28、.Three, the impression of colorWhen we see the color, in addition to feeling its physical impact, the heart will immediately feel, this feeling is generally difficult to use words to describe, we call it "impression", that is, "color impression.". If there is a standard that can

29、reasonably and objectively analyze this difference of perception, then you can use it to illustrate the difference in perception.1, red color impressionRed is a strong color, the color is warm, impulsive, easy to attract attention, so in a variety of media use, in addition to having better photopic

30、effect, are used to convey more energetic, positive, warm, warm, corporate image and spirit on the meaning, in addition also used red as a warning, dangerous, prohibited, fire and other marked with color, people in some places or objects, see red marks, often do not have to look at the content, has

31、been able to understand a warning of danger of Italy, in industrial safety color, red warning, dangerous, prohibited, color of fire. Professor John Eaton, a famous colorProfessor, painted red with different colors. He said: in the crimson red foundation, calm down, in the burning heat; in the blue a

32、nd green ground, red like burning flame; in the yellow green ground, red into a bold, reckless intruder, intense and unusual; in the orange red foundation, seems to have been smoldering dim, without life, it seems like a parched.The big red brick red rose red2, orange color impressionOrange is secon

33、d only to red, so it also has the characteristics of long wavelengths: the acceleration of the pulse and the sensation of rising temperatures. Orange is a very lively color, and it is the warmest color in warm colors,It brings us to the golden autumn, the rich fruit, so it is a rich, happy and happy

34、 color. In addition, orange high visibility, in industrial safety color, orange is warning color, such as the locomotive, mountaineering clothing, backpacks, life jackets, because orange is very bright, sometimes makes people have a negative vulgar impression, this situation is particularly likely t

35、o occur in the design of a type of network station, so in the use of orange, attention should be paid to the choice of color collocation and performance, to orange bright and lively with dynamic characteristics of play.Experience tells us that a little orange with black or white, will becomea steady

36、 and reserved with the bright warm, but with more black, as a burnt orange in color, add more white with a sweet taste. The combination of orange and blue makes up theloudest and most cheerful colors.Orange orange orange orange Sunkist Zhu3, yellow color impressionYellow is the highest color of brig

37、htness and can maintain a high degree of purity in brilliance. The Yellow brilliance, brilliance, and the brilliance of the sun, therefore represent the light of wisdom that illuminates the darkness; yellow has a golden light, and therefore symbolizes wealth and power; it is the color of pride. Blac

38、k or purple foil can makeyellow reach the strength of infinite strength. White is swallowed yellow color, faint pink can also be like a beautiful young girl, yellow, this proud prince to conquer. That is to say, yellow can not bear the erosion of black or white most, these two colors just a little i

39、nfiltration, yellow immediately lose brilliance. In addition, the high visibility yellow in color, industrial safety, yellow is a warning of danger, often used to warn of dangerous or alert, such as the yellow light traffic signal on the large machine engineering, students with a raincoat, rain boot

40、s, use yellow.Rhubarb, lemon yellow, ginger, Huang Mihuang4, green color impressionBright green, very beautiful, elegant, especially with modern technology to create the most pure green, is a very beautiful color. Green is tolerant and generous, and the penetration of blue or yellow is still very be

41、autiful. Yellow green; simpleand young; bluish green; comely and open-minded. Ash green, is also a kind of peaceful color, like the twilight of the forest or in the mist that field. In the design, green conveys relaxed, ideal, hope, growth in line with the impression, service industry, health care i

42、ndustry demandsin the factory in order to avoid the operation of eye fatigue, a lot of work is the use of mechanical green, general medical institutions place, often used to make green space color planning labeling of medical supplies.The green green olive green5, blue color impressionBlue is the co

43、lor of the sky and the sea broad, the vast scenery is blue, or dark blue or light blue, will make us to think of the vastness of the universe or the flow of air, therefore, blue is a symbol of eternity. Blue is the coldest color, reminiscent of the blue projection on a glacier. Blue, in pure conditi

44、on, does not mean emotional indifference; it represents only calmness, reason, and purity. The real emotion is reduced to the cold, sad color, the blue which is muddy. Because of the characteristics, blue calm rational, accurate impression, in the design, emphasis on science and technology, the effi

45、ciency of the goods or corporate image, mostly used when the standard blue color, the color of enterprise, such as computer, automobile, photocopiers, photographic equipment and so on, in addition to blue depression, which is affected by the influence of western culture. This impression is also used

46、 in the design of a literary work or emotional appeals in.Big blue sky blue blue blue6, purple color impressionDue to a strong feminine character, purple is also limited in the design of colors, except for women related goods or corporate image, other types of design are not often used as the main c

47、olor. The shortest visible light is the violet wave. Usually, we think a lot of purple, because red with a little blue or blue, with a little red, will be obviously purple. So it's hard to pin downthe standard purple. Professor Eaton made such a description of the purple is perceived color, myst

48、erious, impressive, sometimes give people a sense of oppression, and by contrast, sometimes menacing, sometimes inspiring. When purple appears in the gamut, it can be marked by a sense of terror, especially in the case of purplish red. "This kind of light projected onto a landscape suggests the

49、 horrors of the end of the world," Gerd said." Purple feeling, I agree with Ni Kuang said, "purple is very ambiguous color, like Cantonese stew in some kind of soup."."Purple is a symbol of devotion. When the dark purple deepens, it is sometimes a symbol of ignorance and sup

50、erstition.The latent disaster often from the dark purple suddenly broke out, once the purple was weakened, when the bright light of the ignorance and understanding the piety of the color, beautiful and lovely iridescence makes us.With purple performance chaos, death and excitement, with blue and pur

51、ple manifestations of loneliness and devotion,manifestation of divine love and spirit with red purple governance field - in short, the performance of somevalue that is purple ribbon.Professor Eaton's description of purple really does give us inspiration, and itseems to be the most negative color

52、 on thecolor ring. Although it does not want to be as cold as blue, the red infiltration makes it appear complicated and contradictory. It is in between the cold and warm, the indefinite state, plus its low brightness nature, perhaps constituted this color to cause in the psychology the negative fee

53、ling. Unlike yellow, purple can hold many levels of desalination. A dark, pure purple, with a small amount of white, becomes a very beautiful and soft color. With the continuous addition of white, it will continue to produce many levels of lilac, and each level of lilac, all appear very soft and tou

54、ching.Large purple wine of noble purple7, brown color impressionIn the design, is usually used to show the original material brown texture, such as hemp, wood, bamboo, cork, or used to convey some fascinating materials that color taste, such as coffee, tea, such as wheat, or emphasize the style of c

55、lassical elegance enterprise or product image.Brown, cocoa, malt, log color8, gray color impressionIn the design, gray with a soft, elegant impression, but also belong to the middle character, both menand womencan accept, so the main color of gray is always popular, in many high-tech products, espec

56、ially related to metal materials, almost all of the advanced science and technology to convey the gray image, the gray level, most of the use of changes of different combinations with other colors or he will not, too, and have a dull, dull, stiff feeling. But gray is the most passive color, it is a

57、neutral color completely, relying on adjacent color gray life, once near the bright warm, calm character will appear; if close to cool, then becomes gentle warm gray. Rather than call it black with the word "pause", it is better to use it in gray, because black and white mixing, mixing wit

58、hout color, and full color mixing eventually lead to neutral grey. Gray means that all the color contrast disappears, is the most stable visual rest point. However, the humaneye cannot keep its eyes on gray for extended periods of time, because endless rest means death.Big blue grey dark grey mouse9

59、, black and white color impressionIn the design, white has advanced science and technology and other impression, usually need to use pure white color collocation, others will bring severe cold feeling, so in the use of white, will be with someother color, such as ivory white, white, white, white apple, in living supplies, the use of color on the dress, white is the main color is always popular, and can make any color collocation.Black has a noble, steady, and impression, many technology products, the use of color, such as TV, car, camera, audio equipment colors, mostly with black, on the ot
