The formal beauty principles of composition include symmetry and balance, contrast and harmony, rhythm and rhythm, change and unity.
The law of formal beauty is the summary of experience and abstract summary of the formal laws of beauty in the process of creating beautiful forms and beauty. Mainly include: symmetry and balance, simplicity and unity, harmony and contrast, proportion, rhythm and unity of change. Researching and exploring the laws of formal beauty can cultivate people's sensitivity to formal beauty and guide people to better create beautiful things. Mastering the laws of formal beauty can enable people to more consciously use the laws of formal beauty to express beautiful content and achieve a high degree of unity between beautiful form and beautiful content.
Aesthetic section, also known as the golden section, was first seen in ancient Greece and ancient Egypt. The golden section is also called the golden ratio and the ratio between inside and outside. That is, a line segment is divided into two segments a and b of different lengths, so that the ratio of the long segment a to the total length (a+b) is equal to the ratio of the short segment b to the long segment a. The ratio is a: (a + b) = b: a, and the ratio is 0.6180339... This ratio is more pleasing to the eye in terms of shape. Therefore, 0.618 is also called the golden ratio.
The constituent factors of formal beauty are generally divided into two parts:
One part is the perceptual material that constitutes formal beauty, and the other part is the combination law between the perceptual materials that constitute formal beauty, or the composition law. , the law of formal beauty. The perceptual materials that constitute formal beauty are mainly colors, shapes, lines, sounds, etc. The physical essence of color is light with different wavelengths. The light that human visual organs can perceive is electromagnetic waves with wavelengths between 390 and 770 nanometers.
Various objects exhibit very complex color phenomena such as red, orange, yellow, green, cyan, blue, and purple due to the different degrees of electromagnetic waves they absorb and reflect light. Color has attributes of hue, brightness, and purity, as well as color differences. Color produces specific stimulating information for people's physiology and psychology, has emotional attributes, and forms color beauty.
For example, red usually appears to be lively, enthusiastic, and exciting; blue appears to be tranquil, heavy, melancholy, and sad; green appears to be calm, steady, and refreshing; white appears to be pure, white, elegant, and sad. ; Yellow appears bright, joyful, etc. As the basic elements that constitute the spatial image of things, shapes and lines also have very distinctive emotional expressiveness.
