Modern society has entered diversification and individualization, and people pay more and more attention to the shaping of personal image. The choice of clothing is often decided according to the quality of color matching, and the cultural and artistic accomplishment of the wearer is evaluated. This paper analyzes and applies the basic principles of color collocation and harmony, as well as the collocation and combination of clothing colors, in order to help consumers understand and master the diverse combination methods of clothing colors, make full use of limited clothing, and wear infinite elegance and taste.

1. Emotional function of clothing color

Color itself has no emotion, but when it is used with the human brain through vision, it can make people have certain emotional effects. If red is reminiscent of fire, it makes people feel warmer; Blue reminds people of the sea and makes people feel refreshed. Thus, through people's association, habits, aesthetic awareness and many other factors, give full play to the role of color to express emotions. For example, in festivals, people use bright colors to express cheerful atmosphere; In film and television works, the feeling of sadness is expressed in a dull cold tone [1]. All these have added infinite fun and beautiful feelings to our lives.

2. The basic method of clothing color matching

As we know, red, orange, yellow, green, blue and purple all have their inherent beauty, such as the purity of white, the freshness of green and the elegance of purple. However, improper color matching will destroy the inherent aesthetic feeling of color itself [2], so we must first understand the combination relationship and combination law between colors in color matching in order to create beautiful visual effects. A set of matching colors should conform to the law of diverse and unified formal beauty: the primary and secondary colors should be clearly defined, and the secondary colors should serve the primary colors without usurping the role of the master.

2. 1 lightness combination method

Pay special attention to the adjustment of hue and purity, and different shades of light colors should be matched. The following three methods roughly summarize the lightness combination of clothing. First of all, the color matching of high-definition colors gives people a relaxed and bright feeling, such as white, beige, khaki and pink. Secondly, if camel, gray and other colors with low lightness are the most suitable clothing colors for middle-aged people, it will form a subtle, solemn and elegant style. Thirdly, the color matching of low brightness colors will make people feel heavy and depressed, and it will also give people a simple and intellectual feeling. At this time, we should pay attention to the contrast of hue, which will be more lively.

2.2 Color matching

The overall design of clothing color is often composed of various tones with different lightness and purity. First of all, we should determine the tone that needs to be matched, and then change the brightness and purity of the color appropriately to make the final effect meet the visual aesthetic requirements. Here we discuss the matching methods: adjacent color matching, similar color matching and contrasting color matching. First, adjacent color matching. Such as yellow and orange, purple and blue, the hue difference is moderate, and any adjustment of lightness and purity will not affect the expressive force of color, which is an error-free color matching method. Second, the same color matching. For example, red and purplish red, blue and purplish blue, if the color difference is too small, it will appear too uniform and lack a sense of hierarchy and rhythm. At this time, it is necessary to compare brightness and purity. Third, contrast color matching. Such as bright yellow and sky blue, red and green, because the hue contrast is too strong, it will give people a feeling of excitement and anxiety, and it is a good choice to use it in stage clothes and sportswear. If you wear it in daily life and want to look soft and natural, you need to reduce the brightness and purity of the color.

2.3 purity collocation

Compared with lightness and hue, purity has less influence on clothing color when matching colors. We only need to master the collocation of hue and lightness, and on this basis, adjust the purity appropriately to make the overall color coordinate. So how should high purity and low purity be matched? When high-purity color matching, it is easy to make people feel too gorgeous. At this time, it is necessary to weaken the contrast between hue and lightness to make people feel comfortable visually, otherwise it will give people a feeling of excitement and anxiety. Therefore, in order to avoid mistakes, high-purity colors should generally be worn in sets, or with black, white and gray. When low-purity color matching, it is easy to feel dull. To break this dullness, we can strengthen the contrast between hue and lightness.

3. The application of color in fashion design

Clothing can be described as a mirror of society, and the colors on clothing also reflect people's aesthetic taste, ideological symbols and so on, which is of great significance in life. Fashion design is a state design and a space design [3]. The color on clothing is the aesthetic form expressed by human body, and the purpose of color decoration is to beautify human body through decoration, not the decorative form itself. People's choice of clothing color, while being restricted and influenced by social morality, civilization and fashion, will inevitably reflect people's respective social status and mental outlook, so color is of great significance to individuals, enterprises and society [4].

3. 1 Clothing color and environment

Clothing color is related to the natural environment. For example, in the long-term cold, dry and windy north, people's clothing colors are relatively calm, such as dark green and dark blue, to adjust the visual nerve's supplementary demand for color vision; In the long-term warm and watery south, there are green shades all year round, so people prefer bright light colors, such as white and sky blue. Urban colors are rich and strong, and clothing colors are mostly gray and subtle; In rural areas, seasonal colors are obvious, with a single yellow-brown color in winter and a single green color in spring, summer and autumn, so bright and strong colors are used in clothing.

3.2 Clothing colors and national taboos

Due to the differences of regional culture and living customs, people all over the world have some taboos in the choice of clothing colors. Egyptians like green, red and orange, but they don't like purple and blue. They like pyramid-shaped patterns with flowers, and it is forbidden to wear clothes with star patterns. Besides clothes, wrapping paper with star patterns is not popular. In Japan, black is used for funerals, and red is used for adult festival and 60th birthday celebration. Many Mongolians like to wear red robes, and girls like to tie their hair with red ribbons. Because red symbolizes intimacy, happiness and victory, while black is regarded as misfortune and disaster, Mongols do not wear black clothes.

3.3 The relationship between clothing color and the wearer

Color is one of the three elements of clothing, and clothing serves people, so the characteristics of consumers located by clothing enterprises, such as gender, age, posture, occupation and other factors, are the basis of clothing color design. If fat people generally wear dark colors, they will look thin, such as black, dark blue and brown. Middle-aged and elderly people generally use calm colors, such as brick red, dark green, dark gray and navy blue. Artists can wear clothes with exaggerated colors to show their personality; White-collar workers are more suitable for neutral tones and will look elegant and capable. In short, the color should change with the change of the wearer, reflecting the dominant position of people in the dress.

4. Conclusion

Each color has its own unique taste. If you don't have much experience in color matching, in order to reduce the probability of making mistakes, you'd better use achromatic color's color matching or achromatic color's color matching method. The essence of clothing color collocation and application is coordination, unity and diversity. There are infinite combinations of clothing colors, and there are also infinite collocation changes of suitable clothing colors.
