Auxiliary coils in logo designs are a common element, often referred to as "guidelines" or "contour lines." These circles can be used to enhance the visual effect of the logo, making it more recognizable and unique.

The design principles of auxiliary cables are as follows: Symmetry and Gradient.

First of all, the principle of symmetry means that the pattern is divided into two equal parts by a straight line so that the pattern is symmetrical at the center point. This design principle is very common in logo design, for example, many bank logos use symmetrical patterns to demonstrate their stability and reliability.

Secondly, the gradation principle refers to the gradation of colors to create a sense of hierarchy. In logo design, the gradation principle is often used to represent a brand's evolution or product line. For example, logos of some car brands use gradient colors to represent the evolution of their product lines from the low end to the high end.

In addition to the above two principles, there are other auxiliary wire design principles, such as repetition and rotation. The principle of repetition refers to the use of the same patterns or elements to create a sense of rhythm and continuity; The principle of rotation is to create a unique visual effect by rotating the pattern.
