Color rhythm
That is, it is obviously characterized by time and movement, and it can perceive the regular and repeated changes of strength and length, which is a formal beauty of order. Through the convergence, overlapping, repetition and transformation of colors, the aesthetic feeling of rhythm and rhythm is formed in the change and gyration of colors. There are generally three forms.
1. Repetitive rhythm reflects the beauty of order through the repetition of unit forms such as points, lines and surfaces of colors. Simple rhythm has the characteristics of short time and repetition to achieve unity, and it pays attention to mechanical and rational beauty.
2. The gradual change of rhythm makes the color change in a series according to a certain directional law, which relatively weakens the consciousness of "beat" and has a long period, forming a flashing color effect with obvious contrast, silent action and repeated climax. The gradual change rhythm has many transitional forms, such as hue, lightness, purity, cold and warm, complementary color, area, synthesis and so on.
3. Diversified rhythms are composed of many simple repetitive rhythms, and their rapidity, dynamics, movements and ups and downs are also restricted by certain laws, which can also be called more complex rhythms. It is characterized by strong sense of color movement, rich levels and changeable forms. However, if it is handled and used improperly, it is easy to produce chaotic "variegated" adverse effects.
Color echo: also known as color association.
Color echo refers to the use of colors in different positions on one or related plane and space, which are interrelated and avoid isolation. By adopting the method of "you have me and I have you", we take care of each other, depend on each other and reuse them, so as to obtain a unified, coordinated and interesting aesthetic feeling of repetitive rhythm. There are usually two color echo techniques:
1. Dispersion method makes one or several colors appear in different parts of the painting at the same time, so that the overall tone is unified in a certain style, such as light blue, light red, dark green and other TINT, with light color as the main tone in a large area and dark color as the contrast color in a small area, becoming a high-tone pastel. At this time, it is best for dark green to appear not only in one place, but in other places, and make some echoes appropriately to produce a situation of mutual contrast. But the color should not be too scattered, so as not to make the picture appear dull, fuzzy, messy and cumbersome.
2. Series method makes one or more colors appear in different planes and spaces of works and products at the same time, forming a series design, which can produce a sense of synergy and integrity.
Color emphasis
Color emphasis: In the process of color matching, sometimes in order to improve the monotony, dullness and boredom of the overall design and enhance the sense of vitality, an emphasized and prominent color is usually set in a certain part of a work or product, which plays the role of finishing touch. In order to attract the attention of viewers, key colors should generally be arranged in the center or main position of the picture. The use of key colors should pay attention to the following points, moderate and moderate:
1, the key color area should not be too large, otherwise it will easily conflict with the main color, offset, and lose the overall unity of the picture. The area is too small, it is easy to be assimilated by the surrounding colors, and it will lose its function if it is not noticed. Only the key colors with the right area can actively cooperate with each other and complement the main colors, so that the colors are unified and bright and complement each other.
2. The main color should be stronger or more contrasting than the basic color.
3, the key color setting should not be too much, otherwise the multi-focus has no focus, and the multi-center layout becomes over-designed, which destroys the effect of different primary and secondary, orderly and disorderly.
4. Not all works are set with key colors.
5. At the same time, the key colors should be balanced with the overall colors.
The basic composition form of color change is a special work form, and its composition and image organization also have corresponding characteristics and basic laws.
The rhythm and focus of color are the key to attract people's attention. Focus color can directly show the focus of packaging design, and the effective jump of rhythm can also help consumers stop their eyes. Therefore, designers must master the skills of using color in packaging design.
