In the cover design, what color best matches the red background? 1, the collocation of red and white hue is the most vigilant, so the fire alarm uses these two colors as decoration. But the warning color must be used with caution, depending on your actual application and proportion. 2. Red and black are also very integrated colors, which are often used in visual decoration, noble, elegant and mysterious. For example, LG's chocolate mobile phone. 3. Red and green are complementary colors, which can also be understood as the highest degree of contrast between them. If used flexibly, the picture will be harmonious and balanced. But you can't use too much, otherwise it will be too tacky, which is also the disadvantage of using too much complementary color. PS: Any color has its special use environment and matching effect. There is no absolute statement. The theory only provides us with a basis, which depends on the user's personal and actual situation. What color should the red poster use as the background to achieve the best effect? With brown clay as the background, the intensity of red can be highlighted, and with some miscellaneous points, the color scheme of the main red art design can be highlighted. The visual effect of the webpage has a great influence on the impression of tourists, so the industry of webpage art has been formed. The following is the color scheme of art design compiled by Bian Xiao. Welcome to reference ~ The color scheme of art design is mostly blue with white and orange, with blue as the main tone. White background, blue title bar, orange buttons or icons as embellishment; Blue sky and white clouds, quiet and tidy feeling. Green is mostly matched with white and blue, with green as the main tone. White background, green title bar, blue or orange buttons or icons as embellishment, green and white, elegant and lively. Orange is mostly matched with white and red, with orange as the main tone. White background, orange title bar, crimson or orange buttons or icons as embellishment, orange lively and enthusiastic, standard commercial tone, so it is mostly used for web page art design of commercial websites. Dark red is relatively heavy, serious and noble, and it needs to be matched with black and gray to suppress the stimulating red, often with dark red as the main tone. Black or gray background, crimson title bar, light gray background of text content. Although the three primary colors have created countless colors, not all colors are suitable for web page art design, and different colors also have their knowledge in collocation. Web design is equivalent to graphic design, and web designers can apply the aesthetic viewpoint in graphic design to it, so the aesthetic viewpoint in graphic design is very practical in web design. In the art design of web pages, the use of colors is especially taboo for dirty, pure, jumping, flowery, pink and so on. Avoid dirty refers to the background and text content contrast is not strong, gloomy background depressing! Avoid pure color means that bright pure color is too strong to stimulate people and lacks connotation. Avoid jumping, even if the color is beautiful, it can't be separated from the whole. Avoiding flowers means that there is a main color running through it. The main color is not the biggest color, but the color that can reveal and embody the theme best. Just like a leader, although he is a minority, he plays a decisive role. Avoid powder means that the light color is obviously clean, but if the contrast is too weak, it will look pale and weak, just like a patient. In addition, blue is pure, green is yellow and red is bright. Designers should not "design for design's sake". No matter how cool the page effect is, no matter how rich the expression is, if it deviates from the user-centered main line, so that users can't grasp the key points and feel the information that the page itself needs to reflect, then even the best picture presentation will fail. First, to learn color matching, we must first understand the color matching ratio. Japanese designers put forward the golden ratio of color matching, 70: 25: 5, in which 70% is the main color used in a large area, 25% is the auxiliary color and 5% is the decorative color. In general, it is suggested that there should be no more than three colors in the picture, and three refers to three tones, such as deep red and dark red, which can be regarded as one tone. Generally speaking, the less color you use, the better. The fewer colors, the simpler the picture and the more mature the work will be. The fewer colors, the easier it is for us to control the picture. Unless there are special circumstances, such as some holiday posters, which need a lively and energetic atmosphere, more colors can make the picture look lively, but the more colors, the colors should be allocated in strict accordance with the color matching ratio, otherwise the picture will be chaotic and difficult to control. Second, understand the relationship between colors. Color matching is a process of mutual echo and harmony between different tones. The relationship between colors depends on the position on the color circle. The closer the angle between tones is, the weaker the contrast is, and the farther it is, the stronger the contrast is. After remembering these six tones, your journey of color matching has already begun, because all colors can be adjusted according to these six basic tones. This is the six-character mantra. Let's talk about the three most common color matching methods. (1) Adjacent colors in the color wheel are adjacent colors. According to the order of red, orange, yellow, green, blue and purple, the adjacent color combinations are red+orange, orange+yellow, yellow+green, green+blue, and so on. Adjacent colors are closely related, very harmonious and soft, and the picture is very harmonious and unified, which can create a soft and warm feeling. Because they are close on the color wheel, the visual impact of this collocation is weak. To give a few examples: these two pictures are basically matched with adjacent colors. The first picture is decorated with an orange, so the overall picture is very soft and harmonious. Therefore, this color matching is often used in home, cotton fabrics, small fresh and elegant clothes, Chinese style and other products that can give people a quiet, soft and traditional feeling. There is also a monochrome matching method in similar color matching, which adopts the same hue and only adjusts the lightness/saturation of the color to get another color. As shown in the above figure, the text color is the result of reducing the saturation/lightness with the background color. The background color is very bright, and the monochromatic collocation technique is adopted, so it will give people an elegant, elegant and quiet feeling. The font of the main title also adopts some deformation to match the whole picture, which makes the whole picture very unified and harmonious. Blue and purple are used in the picture of Tanabata, and the picture is quiet and harmonious. Next to this picture is a monochrome collocation, dark blue+light blue, which unifies the picture with a little traditional feeling. This poster adopts the collocation of red and orange, with orange as the main tone. Different oranges in the background increase the sense of space and make the picture look less monotonous. Deng Chao's surprised expression in the poster, as well as the dotted lines and geometric squares in the background, the fluttering products make the originally stable picture lively, light and full of impact, which shows that the style of the poster is also closely related to each component of the picture. (2) According to the sequence of red, orange, yellow, green, blue and purple, the interval colors are red+yellow, orange+green, yellow+blue, green+purple and blue+red, so it is called interval color. Compared with the adjacent color, the interval hue is far apart on the color wheel, so the visual impact will be stronger than the adjacent color. The interval color is widely used, and it is not as exciting as the impact of 180 complementary color, but it also has a more lively contrast than the adjacent color. In particular, the mutual collocation of red, yellow and blue is widely used and very popular. To give a few examples: this picture is basically a typical blue-yellow color collocation, the picture is very bright and fashionable, and the text is also in harmony with white. Blue itself has a technical style. Blue, yellow and white are perfect here. This picture is a typical combination of three primary colors, red, yellow and blue. The proportion of the picture is well controlled, with blue as an ornament and white as a harmonic buffer, which gives the picture a certain sense of space. The collocation of purple and green is very bright and slightly traditional, which is a neutral collocation method. The colors of red, yellow and wild have a very striking sense of promotion. You can see that the background of the above picture is not a single color. For example, the last poster, red background and crimson radioactive background. In the third poster, some purple geometric squares are added behind the purple background. Although they are two colors, they all belong to the same tone, which can make the picture get rid of monotony, increase the sense of space and give people a lively and fashionable feeling. Color matching must control the color ratio of the picture! Focus on red and blue collocation: red and blue collocation is widely used, because these two colors are typical cold and warm colors, which will leave a deep impression on people. For example, the logo of Baidu, the logo of Pepsi, the police car of the Public Security Bureau, Superman, the cartoon image of Spider-Man and the national flags of many countries. The contrast between these two colors can easily lead to visual fatigue and mental excitement, so it is not suitable for still life such as home. Because the impact of red and blue is too strong, white is the most common color, and the most typical one is the Logo of Pepsi. Find a corporate service and go to Pig Bajie.
