Color is one of the three elements (color, shape, icon) in traffic signs and logos. Different colors have different wavelengths, and the wavelengths that our eyes receive are limited in their range, so we have chosen them as traffic signs. Visibility must be strong. At the same time, according to the different psychological and physiological effects of different colors on people, and the purpose that the logo needs to achieve, choose the corresponding color. The key to choosing color is that people can notice it from a long distance, and at the same time stimulate them to make some reactions through the effect of color, and this also achieves the role of color in the design of signs and logos. Reasonable color design can help us design more reasonable and more humane road traffic signs and signs.
In fact, city signs and signs are not only a sign or communication object for identifying directions, finding roads, and identifying public facilities, but more as reflecting the cultural characteristics of a region, a city, a region, a group, and a city. Important factor. The success of a sign depends to a large extent on the rationality of the sign design, and color design is the most difficult factor to accurately grasp in the design of urban signage. A good sign work should coordinate the color plan with the surrounding environment, and use color to highlight the personality of the work. Secondly, the signs should be coordinated with the surrounding building tones. If the buildings of a city are presented in a gray tone, although there is a peaceful effect, but there is no bright color, then the whole city will appear to be devoid of vitality. And when the logo system is dotted with pure colors in the city, then the city will add a lot of visual highlights, thereby deepening people's impression and improving people's overall impression of the city. It can be said that color makes the world we see more attractive. While satisfying the basic functions, it also improves our aesthetic pursuit invisibly. Color is everywhere in life. It is not only used in traffic signs and signs, but also in all aspects of life.
