[Edit this paragraph] The laws of formal beauty mainly include the following:
Harmonious
Everything in the universe, despite its ever-changing forms, exists according to certain laws, from the movement of the sun and the moon to the movement of the planets to the composition and movement of the atomic structure. Einstein pointed out that the universe itself is harmonious. The broad interpretation of harmony is that when judging the relationship between two or more elements or parts, the feelings and consciousness of each part are a whole coordinated relationship. The narrow interpretation of harmony is that unity and contrast are not boring or chaotic. A single color, a single line does not matter harmony, only a few elements have basic * * * commonness and compatibility can be called harmony. For example, a set of coordinated color blocks, some orderly approximate graphics and so on. The harmonious combination also maintains some differences, but when the differences are strong and significant, the harmonious mode changes into the comparative mode.
Contrast and unity
Contrast, also known as contrast, refers to the phenomenon that two visual elements with great contrast are successfully listed together, which makes people feel distinct and strong, but there is still a sense of unity. It can make the theme more vivid and the visual effect more active. The contrast relationship is mainly through the lightness and coldness of visual image tones, the saturation and unsaturation of colors, different tones, the size, thickness, length, straightness, height, concavity and convexity, width, vertical direction, horizontal direction and inclination, quantity, arrangement density, up and down, left and right, height and distance of position, virtual shape, black and white and light. It embodies the contradictory and unified world view in philosophy. Contrast rule is widely used in modern design and has great practical effect.
symmetrical
Symmetrical forms can be seen everywhere in nature, such as the wings of birds and the leaves of flowers and trees. Therefore, the symmetrical form has a natural, stable, unified, coordinated, neat, elegant, solemn and perfect simple aesthetic feeling visually, which conforms to people's visual habits. Symmetry in plane composition can be divided into point symmetry and axial symmetry. Suppose a straight line is set in the center of a graph and the graph is divided into two equal parts. If the shapes of the two parts are completely equal, the figure is axisymmetric, and this straight line is called the axis of symmetry. Suppose a graph has a central point and rotates around this point to get the same graph, which is called point symmetry. Point symmetry includes centripetal symmetry, centrifugal emission symmetry, rotational symmetry, inverse combination symmetry, concentric circle symmetry extending layer by layer from the center of the circle, etc. The application of symmetry principle in plane composition should avoid monotony and dullness caused by excessive absolute symmetry. Sometimes, adding some asymmetric factors into the overall symmetrical pattern can increase the vividness and beauty of the composition layout and avoid monotony and dullness.
weighing apparatus
The weight borne by both ends of the weighing instrument is supported by a fulcrum. When the two sides are in mechanical balance, it is called balance. The balance in graphic composition design is not the equivalent relationship between actual weight and moment, but the balance that acts on visual judgment according to visual elements such as image size, weight and color. Plane composition usually takes the visual center (the midpoint of the place with the strongest visual impact) as the fulcrum, and each component maintains visual balance with this fulcrum (as shown in the figure). In real life, balance is a dynamic feature, such as human movement, birds flying, wild animals flying, wind and grass, waves of running water and so on. , are in the form of balance, so the composition of balance is dynamic.
proportion
Proportion is the quantitative relationship between parts or parts and the whole. This is an accurate and detailed ratio concept. In the long-term production practice and life activities, people have been using the proportional relationship, based on the human body's own scale, and according to the convenience of their own activities, summed up various scale standards, which are reflected in the manufacture of utensils and tools for food, clothing, housing and transportation. For example, the golden ratio 1: 1.6 18, which was discovered as early as ancient Greece, is the ratio of height to width of human eyes. Proper proportion has a harmonious aesthetic feeling and becomes an important content of the law of formal beauty. The proportion of beauty is an important factor in the size of all visual units and the arrangement and combination between units in the plane composition.
centre of gravity
In physics, the center of gravity refers to the point where the resultant force of gravity acts on all parts of an object. The common methods for finding the center of gravity of general objects are: hanging the object with a line, and the center of gravity must be on the suspension line or the extension line of the suspension line when balancing; Then hold the other point of the messenger wire. After balancing, the center of gravity must also be on the new suspension line or the extension line of the new suspension line. The intersection of the front and rear lines is the center of gravity of the object. In plane composition, the position of the center of gravity of any shape is closely related to the stability of vision. The relationship between human visual stability and formal beauty is complex. When people's eyes touch the picture, they often quickly go from the upper left corner to the lower left corner, then through the central part to the upper right corner and then back to the most eye-catching central circle in the picture. This center point is the center of vision. However, the change of picture outline, the gathering and scattering of graphics, and the distribution of color or light and shade can all affect the visual center of gravity. Therefore, the treatment of the center of gravity of the picture is an important aspect of discussing the composition of the plane. In print advertising design, the theme or important content information to be expressed by an advertisement should not deviate too far from the visual center of gravity.
Rhythm and prosody
Rhythm refers to the change and repetition of the priorities of sound beats in music. Rhythm, a term with a sense of time, refers to the sense of movement when the same visual element is repeated continuously.
Rhythm originally refers to the rhythm and rhythm of music (poetry). The combination of high and low tones, light and heavy tones and long and short tones in poetry, symmetrical pause or pause, repetition of the same tone in a certain position, and the use of homophones at the end of sentences and lines to enhance the musicality and rhythm of poetry are all the use of rhythm. Simple unit combination and repetition in plane composition are often monotonous, and images or color groups that change regularly are arranged in a number ratio and equal ratio, which makes them have a sense of melody of music and poetry. This is rhythm. Rhythmic composition has positive vitality and energy, which can enhance charm.
Association and artistic conception
The picture composed of graphics achieves a certain artistic conception through visual communication and association. Association is an extension of thinking, extending from one thing to another. For example, the color of graphics: red makes people feel warm, enthusiastic and festive; Green reminds people of nature, life and spring, thus giving people a feeling of calmness, vitality and spring. Various visual images and their elements will have different associations and artistic conception, and the symbolic meaning of the resulting graphics, as an expression of visual semantics, is widely used in graphic design composition.
