Knowing the three attributes of color can make the color match freely, and using five roles well can make the color match fresh and clean. 1, color three attributes When we get lost, we will use a map or compass to measure the position at that time; When we match colors, we will use three attributes of colors to detect the position of colors. So what are the three attributes of color? The essence of color is composed of hue, lightness and purity, which are called three attributes. 1. 1 Hue (hue) Hue is the primary feature of color and the most accurate standard to distinguish different colors. In fact, any color except black, white and gray has the property of hue, and hue is composed of primary color, intermediate color and composite color. Tone, texture and appearance that color can present. Different colors in nature are infinitely rich, such as purplish red, silver gray and orange yellow. Hue is the appearance title of various colors. The characteristics of hue depend on the spectral composition of light source and the perception of human eyes caused by the proportion of radiation with various wavelengths reflected from the surface of colored objects. When measuring color, it can be expressed by hue angle h and main wavelength λd(nm). In polymer, it is the color sense corresponding to the main wavelength and complementary main wavelength expressed according to XZY series colors. Generally, compared with the standard color solution in molten state, the consistent color scale is called hue number. Because there are many kinds of polymers, there are many standard color systems. The commonly used standard color systems are all prepared in accordance with the methods specified in national standards. 1.2 lightness (brightness) refers to the brightness of a color, which depends not only on the intensity of the light source, but also on the reflection coefficient of the object surface. The difference of color lightness includes two aspects: first, it refers to the change of the depth of the same tone, such as light green, medium green and dark green; Second, it refers to the brightness difference of different hues. Like saturation, the brightness of different hues is different. Among all visual colors, yellow has the highest brightness, while purple and blue-purple have the lowest brightness. The brightness of colored objects is related to the surface structure of the objects. If the surface of the object is rough, its diffuse reflection will reduce the brightness of the color; If the surface of an object is smooth, total reflection will make the color brighter. 1.3 purity (saturation) purity usually refers to the brightness of a color. From a scientific point of view, the brightness of a color depends on the single degree of light emitted by this hue. All colors with monochromatic light characteristics that can be distinguished by human eyes have a certain vividness. Different shades not only have different lightness, but also have different purity. In addition, chemical reagents are also divided into purity. Purity is also called color saturation, that is, the ratio of color components to achromatic components (gray scale) contained in a color determines the purity and vividness of a color. When there are many color components in a certain color, the color will be unsaturated, the color will appear dim and the visual effect will be weakened. The purity of primary colors is the highest, and the more mixed colors, the lower the purity of mixed colors. For example, high-purity red, if different degrees of gray are added, its purity will be reduced and the visual effect will be weakened. Among all visual colors, red has the highest purity and blue has the lowest purity. 2, understand the three primary colors 2. 1 color stereogram purity After adding gray to bright orange, it becomes brown and then becomes gray. The original bright orange gradually darkens, and the lightness of the color is called purity. Brightness colors can be divided into light colors and dark colors. Therefore, we introduce the concept of lightness and use lightness ruler to measure the lightness of color. Suddenly narrowed his eyes, it is easy to distinguish the brightness of bright red, green and other colors. Hue, such as red, blue and yellow, is called hue. From the circumference, you can clearly see which color is in contrast and which color is adjacent. 2.2 How to remember the three attributes With the help of circles and triangles, it will be easier to understand the three attributes. Hue is understood by circles. Just remember the three primary colors red, yellow and blue, and the orange, green and purple in the middle. Tone presents a fixed relative position, and the three primary colors of red, yellow and blue are arranged in a triangle with orange, green and purple in the middle. As for lightness and purity, we should understand the relationship between pure color, bright color, dark color and turbid color through triangle tone diagram. Mastering these, you can match the ideal color. First, paint the vertices of the triangle with black and white. Gray is between white and black. There is a bright color between solid color and white, and a dark color between solid color and black. The middle part is black. There are seven different shades. 2.3 Hue Mastering the hue circle through six colors can help us understand hue. The most basic colors are three primary colors, namely red, yellow and blue. Add orange, green and purple at the same time, and a 6-color separation ring will appear. In the meantime, you can also add 12 hue and 24 hue. At present, six colors can be mastered. In hue diagram, the relative color is called contrast color, for example, the contrast color of red is green. Similar colors are called adjacent colors, for example, red adjacent colors are purple and orange. Homochromatic system refers to a mixture of white or black with the same tone. The effect of hue The effect of color itself includes warm colors (red, orange, yellow, etc. ) gives people a warm and energetic feeling, as well as cool colors (blue, etc. ) That gives people a cool and quiet feeling. In addition, controlling chromatic aberration can also change the impression of color. For example, using contrasting colors will make the picture more vivid. Which of the following pictures looks more vivid? The answer is B.A. The picture is full of green scenery, and the color difference is relatively small, and only the color matching of adjacent colors is used, giving people a quiet and steady impression. In addition, the contrast color of red with green is added to the B picture, so that green becomes vigorous and powerful, and the whole picture becomes vivid and impressive. Warm colors and cool colors can be roughly divided into cool colors, warm colors and neutral colors. Neutral colors include green and purple. The color difference effect of warm color, cool color and neutral color distribution map adopts the same color and adjacent color matching, which makes people feel stable and practical. On the contrary, enlarge the color difference and add contrast color, and the picture effect will be more prominent. 2.4 Brightness The brightest color in the scale color of lightness is white, the darkest color is black, and the middle is gray. From almost white light gray to almost black dark gray, it is the scale of lightness, which we call gray scale. The effect of lightness itself means that lightness is light and darkness is dignified. Which of the following pictures looks dignified? The answer is B, because figure B increases the brightness difference, gives a sense of manpower and loses elegance; While figure a reduces the brightness difference, thus showing elegance and high quality. In addition, increasing brightness difference can achieve dynamic effect; Reducing the brightness difference will achieve a stable effect. Brightness position with bright color as the main body, bright and cheerful; With dark color as the main body, it is thick and calm. The brightness difference reduces the brightness difference and is elegant; Enlarge the brightness difference and show vitality. 2.5 Purity Purity Brightness is high and turbidity is low. This measurement of color brightness is called purity. Understanding hue helps us to make better use of purity. Tone is produced by the intersection of purity and lightness. If you cut the color stereogram vertically, you can see the blurred tones. We don't say whether the tone is high or low, but we should use words such as light and shade to describe it. Tone determines the feeling of color matching. Tone can also be understood as the state of color, which refers to the feeling and atmosphere that color gives people, and is the decisive factor that affects the visual effect of color matching, so we must pay full attention to it when matching colors. Even if the color tone changes, the color tone of the same coordinate in the plane triangle of the color stereogram is the same, giving people the same feeling and being in the same state. (Above) Which product in the picture below can give people a sense of calmness? The answer is B. Because the product in Figure B belongs to dark tone, dark tone can give people a sense of stability and composure; The overall color of the product in Figure A is light, which makes people feel that the product is mainly children, giving people a gentle and comfortable feeling. The position of hue plays a great role in the feeling of color matching. Tone difference is small, so it is stable and harmonious, and the difference is big, so it changes. 3. What are the five roles? Just like novels, TV plays and movies, color matching also pays attention to various roles. Only when the role of a certain color is put right can the overall picture show a stable feeling. There are five basic roles, and mastering them helps to match the perfect color. 3. 1 protagonist It is not difficult to see from the literal meaning that it is the central color of color matching. Choose other colors according to the protagonist. Decide the subject to make the whole picture stable. The protagonist should use the strongest color. If this strong color is consistent with the protagonist, it clearly shows the center and the color is refreshing and stable. The position of the protagonist can be in the center of the picture or in the corner. When an object is strongly colored, it will become the protagonist. Which of the following pictures has a calm and capable color scheme? The correct answer is B. Because the red color in the center of Figure B becomes the protagonist of the picture, it plays an emphasis role, and the picture becomes bright, calm and capable with a strong protagonist as the center; The protagonist in picture A is yellow, lacking a competent protagonist, and the picture is sloppy. If the protagonist is colorful and impressive, the smaller the area, the better. In particular, giving the protagonist high-purity colors will stabilize the overall picture. For example, the beverage bottle in Figure A lacks the main function and is not emphasized, which is disturbing. The beverage bottle in Figure B is orange with the protagonist, and the overall picture is much more calm. 3.2 Matching roles (highlighting colors) The role of matching roles is to set off the protagonist and make the protagonist more prominent. Contrast colors brighten the protagonist. When a matching character is added next to the protagonist, the picture is instantly vivid and full of vitality. That's because the hue of the matching role is opposite to that of the protagonist, which plays a very good role in highlighting the protagonist. The dim contrast color highlights the hue of the protagonist according to the hue circle, making the protagonist more vivid and prominent. The smaller the matching role area, the better the effect. It should be noted that if the matching role area is too large or the purity is too high, the main role will be weakened. Proper purity and area will have a good effect. 3.3 Main color (background color) The main color is the color around the background of the whole picture. Even if the area of color is small, it can dominate the overall feeling of the picture. The background color dominates the overall feeling of the picture. Even if the protagonist is the same, if the background color is different, the feeling brought by the picture is different. The looming background color behind the protagonist actually dominates the whole picture effect. Although the protagonist is the center of color matching, he is often quite weak in front of the background color. What do the following two pictures give you? In Figure A, smooth and bright yellow is used as the background color, and the picture has a quiet atmosphere, while in Figure B, high-purity big red is used as the background color, and the picture is immediately promoted and highlighted. The main color determines the feeling of the protagonist. If the protagonist is different, the background color is different, and the feeling brought by the picture is different. The dark red background color in Figure A matches the black color of the product, giving the picture a sense of strength. The yellow-green background color in Figure B matches the green color of the product, giving people a refreshing feeling. A small area of the main color can also achieve the effect. Even if the background color is small, it can become the main color as long as it surrounds the main body. No matter how small the area is, it can affect the overall feeling of the picture. Dominance has nothing to do with color power. Background color has nothing to do with color strength. Dim colors darken the whole picture, while bright colors brighten the whole picture. 3.4 When the main characters of the fused color are separated from other colors, the homologous color is placed at the separated place to play the role of fusing the whole. Ease Free Colors When we are matching colors, when strong colors are too strong, or when one of the colors is too prominent, we add fusion colors to relax and stabilize the picture. Which of the following two pictures uses the fusion color? The correct answer is B. The red color of the cone in the center of Figure B echoes the red color of the scattered cherries, blending the whole. However, the cone color in Figure A is similar to the background color, which is not eye-catching. The surrounding red is in a free state, and the picture loses its fusion relationship. The effect of color mixing is that the same hue nearby can control the main characters and integrate the whole. 3.5 Emphasize color If you add a small area with strong color to the picture, the picture will be more vivid and vivid. Emphasizing color can make the picture vivid. When the color scheme of the picture has not changed, you can try to add an accent color. You will find that the picture after joining is full of vitality. Which of the following two pictures looks more vivid? The correct answer is B. In Figure A, the blue of the camera and the blue of the background are the same color, and the picture has no color change, which is too simple and unobtrusive. In Figure B, the orange of the camera and the blue of the background are contrasting colors, which play an emphasis role, and the whole picture presents a cheerful atmosphere. This difference is to emphasize the effect of color. Emphasize that the stronger the color, the smaller the area and the better the effect. Strong color matching is a high-purity contrast color, and the better the effect. Summary: When you correctly understand the three attributes of color (hue, lightness and purity), you can freely match colors. If you want to match fresh and clean colors, you need to master five roles (main role, matching role, leading color, blending color and emphasizing color). There are actually ten roles, but you only need to master the five introduced in this article. The other five roles are connected color, mosaic color, balanced color, added color and advanced color.
