人的视觉感知是具有闭合需要的。当视知觉遇到不完全（图形）的刺激时，会有意无意地补充其中缺失的部分，并把它作为一个整体识别。北京设计公司在标志设计时可以利用闭合这一特性，有意将标志符号残缺或断裂一部分，让观者自觉不自觉地填充残缺部分。这种使观者的视知觉参与其标志符号完整的过程，是有效地提高视知觉印象和视知觉记忆的一种方法。设计公司标志设计中的错视现象。People's visual perception is closed. When visual perception encounters incomplete stimuli, it intentionally or unintentionally complements the missing parts and recognizes them as a whole. Beijing Design Company can make use of this characteristic of closure in logo design, intentionally make logo symbols incomplete or broken part, let the viewer consciously or unconsciously fill the incomplete part. It is an effective way to improve visual perception impression and visual perception memory. The wrong look phenomenon in logo design of the design company.当视知觉条件成立时，它在一定范围内会保持稳定，视知觉这一特性对维护人的正常生存是不可缺少的。但是，在有些视知觉条件下人们也会对客观的事物产生主观的的视觉判断错误，即我们的视知觉不能准确地反映外界事物特征，而出现种种歪曲。When the condition of visual perception is established, it will remain stable in a certain range. This characteristic of visual perception is indispensable to the normal survival of human beings. However, under some visual perception conditions, people will also make subjective visual judgment errors on the objective things, that is, our visual perception can not accurately reflect the characteristics of external things, and there are various distortions.如狭窄的房间在墙体上安装一面镜子会使人感觉房间宽敞了许多，身体肥胖的人穿竖条纹或深色的衣服会使人显得瘦一些等这些都是错视现象。研究错视现象对设计公司标志设计有一定的实践意义。错视现象从消极方面看，它有碍于人们正常的视觉活动；从积极方面看，在标志设计的表现中可利用这种现象来达到某种特殊的艺术效果。下面分类说明：Such as a narrow room on the wall to install a mirror will make people feel that the room is much more spacious, obese people wearing vertical stripes or dark clothes will make people look thinner and so these are mistaken phenomena. It is of practical significance to study the wrong look phenomenon for logo design of the design company. From the negative aspect, it hinders people's normal visual activities; from the positive aspect, it can be used in the performance of logo design to achieve a special artistic effect. The following classification explains:A、大小、长短方面的错视：A, size and length:两条相等长度的线段，组合为“T”状，垂直线看起来比水平线长。Two lines of equal length are combined in the form of "T", and the vertical line looks longer than the horizontal line.
在两条相等长度直线的两端，各加上向外、向内的箭头，结果在视觉上这两条长度相等的直线就会产生长短变化。同样的两个正方形，其中一个旋转方位，这样就会给大小不同的感觉。两个面积相等的圆形，一个在更大圆形的包围之中；一个在较小的圆形包围之中，结果前者显得小，后者显得大。At both ends of two lines of equal length, each with an outward and inward arrow, the result is a visual change in the length of the two lines of equal length. The same two squares, one of which rotates azimuth, will give a different sense of size. Two circles of equal size, one surrounded by a larger circle, and one surrounded by a smaller circle, result in the former being smaller and the latter being larger.B、形状方面的错视：B, wrong look in shape:两条平行线段由于附加放射状线段的影响而看成不平行。在许多环形曲线中，正方形的四边略显弯曲。Two parallel lines are regarded as non parallel because of the influence of additional radial lines. In many circular curves, the square of the four sides is slightly curved.C、色彩方面的错觉：在色彩方面的错视，表现为明度高的色彩使人有舒张感，明度低的色彩给人一种收缩感。在设计公司标志设计中经常应用错视规律来创造引人注意的标志。例如，在设计公司标志设计中将一个二维的几何形利用错视原理或色彩的变化制造成三维形体，就能产生很好的视觉效果；在设计公司标志设计配色中，将两块色的一部分进行交叉处理，以达到视觉混色，从而在视知觉上制造出“第三块色“的效果等。我们了解错视现象的一般规律，就可在标志设计中主动避免不应有的错视现象，消除消费者对标志视知觉的曲解因素，确保标志信息的准确传达。，气闭，中风，口眼歪斜，疟疾，热病，感冒，瘿气，落枕，荨麻疹。C, color illusion: in the color of the mistake, the performance of high brightness of the color makes people have a sense of relaxation, low brightness of the color gives a sense of contraction. In the logo design of the design company, the wrong look rules are often applied to create noticeable signs. For example, in the logo design of a design company, a two-dimensional geometry can be made into a three-dimensional shape by using the principle of misplacement or color change, and good visual effects can be produced; in the logo design and color matching of a design company, part of the two colors are cross-processed in order to achieve visual mixing, thus creating visual perception. The effect of "third colors" is obtained. Understanding the general law of the phenomenon of mistake, we can take the initiative to avoid unnecessary mistake in logo design, eliminate the distorted factors of consumers'visual perception of logo, and ensure the accurate transmission of logo information.
