1、色彩三要素及色彩对比（The three elements of color and color contrast）The basic type of the contrast of hue.More than two kinds of colors, color contrast effect due to the formation of different hue called hue contrast. It is a fundamental aspect of color contrast, the contrast degree depends on the distance be
2、tween the hue in the hue on the ring (angle), distance (angle) the smaller the contrast is weak and more strong contrast.1. zero contrast(1) no color contrast color contrast although colorless phase, but their combination with great value in practical. Such as black and white, black and gray, gray a
3、nd light gray, or black and white and grey, black and dark gray and light gray etc. Effect of contrast, feeling generous, solemn, elegant and modern, but also easy to produce too sober sense of monotony.(2) no color and contrast color such as black and red, grey and purple, or black and white with y
4、ellow, white and blue and grey. Effect of contrast feeling both elegant and lively, no color area, is elegant and dignified, color size lively sense of strengthening.(3) different brightness or different purity change compared to the same hue contrast a hue, commonly known as sister color combinatio
5、n. Such as blue and blue (blue and white) color contrast, orange and coffee (orange + grey or green) and powder green (green + white) and green (green + Black) color contrast. Effect of contrast feel unified, quiet, elegant, subtle, and stable, but also easy to produce defects of dull and stiff.(4)
6、no color with the same colour as compared to white with dark blue and light blue, black and orange and brown contrast, the effect of the (2) and (3) types of advantages. You can have a certain level, and generous, lively and stable.2. harmonic contrast(1) compared to two to adjacent color contrast c
7、olor hue central adjacent hue, a distance of about 30 degrees, for the weak contrast type. Such as orange and orange and yellow orange contrast etc. The effect of feeling soft, harmonious, elegant, quiet, but also feel monotonous and boring, fuzzy, weakness, must be adjusted to enhance the effect of
8、 lightness difference.(2) a similar hue contrast hue contrast distance of about 60 degrees, for the weak contrast type, such as red and yellow orange contrast etc. The effect is rich, lively, yet unified, elegant, harmonious feeling.(3) the difference in color than the color contrast relative to a d
9、istance of about 90 degrees, in contrast to the type, such as yellow and green contrast effect, bright, lively, full, exciting feeling, interest, are compared with the considerable efforts, but not disorder and sense.3. strong contrast(1) contrast color relative colorimetric relative distance of abo
10、ut 120 degrees, strong contrast type, such as yellow and purple red contrast etc. The effect of strong, bold, strong, lively and rich, but also not easy to unity and sense of confusion, irritation, cause visual fatigue. The general need to adopt various means to improve the harmonic contrast effect.
11、(2) contrast color hue contrast distance 180 degrees, extreme contrast type, such as red and blue green, yellow and blue purple contrast etc. The effects of the strong, dazzling, loud, very powerful, but if handled properly, easy to produce immature, primitive, vulgar, unstable, uncoordinated and ba
12、d feelings. two basic types of brightness contrastMore than two kinds of color combination,Because of the color contrast effect of different brightness formed called brightness contrast. It is an important aspect of color contrast, color scheme is decided to feel bright, clear, dull, soft, strong, h
13、azy and the key.The contrast depends on the color in the color brightness arithmetic series, usually 1 - 3 designated as low brightness area, 8 - 10 as 4 - 7 of Gaoming District, designated as in lightness area. (Figure) in the choice of color combination, when the base color and contrast color dist
14、ance in 5 level and above, called long (strong) comparison, 3 - level 5 called in contrast, 1 - level 2 called short (weak) contrast. It can be divided into nine basic types of brightness contrast(1) high long tones such as 10:8:1, of which 10 were shallow base color, large area, 8 with light color,
15、 area is larger, 1 dark contrast color, the area should be small. The light and dark contrast, sensory stimulation, lively, active, lively, strong.(2) high school profile such as 10:8:5, the brightness contrast is moderate, the feeling is bright and pleasant, clear and bright, stability.(3) high sho
16、rt tones such as 10:8:7, the weak light and dark contrast, image resolution, feeling less pale, soft, elegant, noble, soft, hazy, feminine.(4) in long tones such as 4:6:10 or 7:6:1, the adjustable in lightness color tone, with color, compared with light or dark, feeling strong, steady, vivid masculi
17、ne.(5) in regulating such as 4:6:8 or 7:6:3, the notes in contrast, feeling rich.(6) in the short tone such as 4:5:6, the adjustment for weak lightness contrast, subtle, flat, fuzzy feeling.(7) low long tones such as 1:3:10, the dark and strong contrast, feel magnificent, deep, alert, explosive.(8)
18、low notes such as 1:3:6, the dark contrast medium, feel heavy, simple, conservative, male.(9) low short tones such as 1:3:4, the dark and weak contrast, dull, melancholy, loneliness, mystery, horror.In addition, there is a comparison of the strongest 1:10 the most long, strong feeling, simple, blunt
19、 and sharp glare, etc. three basic types of purity contrastMore than two kinds of color combinations, the color contrast effect of different purity formed called the purity of comparison. It is another important aspect of color contrast, but because of the more subtle, intrinsic, so it is easy to be
20、. In the color design, the purity of comparison is gorgeous, elegant, decided tone feel simple, vulgar, implicit and not key.The contrast depends on the color distance in the color purity arithmetic, the longer the distance between the stronger and weaker contrast.If the gray to bright color is divi
21、ded into 10 pure arithmetic series usually 1 - 3 classified as low purity, 8 - 10 designated as high purity, 4 - 7 as in pure region (Figure). In the choice of color combinations, when the base color and contrast color distance in 5 level and above, is called a strong contrast; 3 - level 5 - 1 calle
22、d in contrast; Level 2 is called weak contrast. It can be divided into nine basic types of purity.(1) fresh stresses such as 10:8:1,The feeling is bright, vivid and lively, beautiful and strong.(2) fresh notes such as 10:8:5, feel more stimulation, more vivid.(3) fresh weak tone such as 10:8:7, beca
23、use of the color purity are high, after the combined comparison each plays a role to resist, collision, feeling so harsh, vulgar, childish, primitive, hot. If the distance from each other, this effect will be more obvious and intense.(4) stressed that such as 4:6:10 or 7:5:1, feel appropriate and po
24、pular.(5) in regulating such as 4:6:8 or 7:6:3, feel the gentle, static and comfortable.(6) the weak regulation such as 4:5:6, flat, vague, monotonous feeling.(7) grey stressed such as 1:3:10, feeling generous, elegant and lively.(8) the grey tone such as 1:3:6, quiet, more generous, feeling each ot
25、her.(9) grey stressed such as 1:3:4, feel elegant, delicate, beautiful, subtle, hazy, weak.In addition, there is a weak contrast color, such as white: black, dark gray, light gray, color purity due to the contrast is zero, so the feeling is very generous, dignified, elegant, simple. position area an
26、d contrast colorAs the carrier of the visual form of color, always has a certain area, therefore, in this sense, the characteristics of the area is also an indispensable color. Although there are more suitable for color selection often in practice of art design, but because of the size, position con
27、trol caused by improper fault conditions.The relationship between 1. color contrast and area(1) color combination, only the same area of the color can be compared to the actual difference, confrontation between each other, relatively strong contrast effect.(2) between the two sides of the same attri
28、bute, a large area, the area has advantages, and the other side to narrow the area, will weaken the color contrast.(3) the color property unchanged, as the area increases, to strengthen the visual stimulus strength, otherwise weakened. Therefore, a large area of contrast color can cause glare effect
29、. As in the environmental art design, general building exterior wall, interior walls are used sophisticated, low purity of color, in order to reduce the contrast intensity caused by bright and comfortable effect.(4) large area color stability, in contrast, the color of illusion effect; on the contra
30、ry, the color illusion effect.(5) the same properties and the area of the color, and the shape of the accumulation and dispersion state relationship is its great stability, high degree of aggregation by its shape color effect, a high degree of attention, and vice versa. Such as outdoor advertising a
31、nd posters, general colors are more concentrated, in order to achieve remarkable effect.The relationship between 2. color contrast and position(1) between the two sides of the color contrast effect is more closer, although, whereas the more weak.(2) a mutual contact, the starting state, the contrast
32、 effect is stronger.(3) all surrounded by another color, the strongest contrast effect.(4) in the work, usually will focus on color settings in the visual center, the most conspicuous. Such as the 4 intersection points of well shaped composition. texture contrast colorThe properties of the material
33、and the color and the image of an object surface texture is close, color feeling is the surface effect of tactile texture and visual feeling.(1) between the two sides of the color, such as the use of different texture of the material, then compare the effect of temperament and more.(2) the same colo
34、r or similar color matching, texture material changes can be used to compensate for the monotony of heterogeneity. If the same red roses printed on thin nylon sand windows and thick sofa fabric, which is composed of decorative effect, as in series, and the charm of color change of material.(3) paint
35、ing and color performance, application of various pigments and painted out can produce different texture effects, such as painting, watercolor, gouache, acrylic and other colored pigments and crayons, McDonalds, pen, brush and other various types of brushes.(4) the same pigment with different ways t
36、o create many wonderful texture effects, to enhance the color of interest, feeling. Such as extension, cracked, and anti pull, and sprinkle, sprinkle, coating, coating, dye, hook, spray, tie, ice, brush, etc., including color technique. six successive contrast color(1) occurred within the same time,
37、 with a view of color contrast is called color and contrast. In this case, comparison and contrast, rejection and effect of color are interdependent. As in the yellow paper on a bit of gray, this feeling is stronger, the so-called color illusion. Another example of black paper coated with a grey whi
38、te box, with the same area and shades of gray squares, and contrast visual feel is gray black paper more bright, forming a so-called lightness illusion.(2) color contrast occur at different time and different perspective, but also has fast time continuity, continuous natural numbers as color contras
39、t.The human eye has the same look at the second color, second color illusion will happen. When the first look longer, the greater the effect. Second color illusion tend to have the complementary color before. This phenomenon is visual afterimage and visual physiological and psychological self balanc
40、ing instincts. Such as the environment of operation room hospital surgery and medical and nursing staff work clothes are selection of blue and green, apparently in order to and blood red, a continuous contrast the clever use of color, the doctor looked at the blue green, not only can reduce fatigue, restore vision, but also easy to see the small blood vessels and nerves, thus to ensure the accuracy and safety of the operation.
