[Guide] In order to facilitate work, the partner can use the color label card agreed in advance for comparison, that is, to determine the comparison benchmark, and then achieve the ultimate consensus through color difference control. In most cases, everyone feels by visual inspection, but everyone has a certain difference in the perception of color. When it comes to requirements in this regard, it is recommended to be more accurate and standardized through the detection and comparison of instruments.
The paint color of the surface of the motor produced by different manufacturers will be different, and the requirements for the paint color of the surface of the motor are different in different occasions. In most cases, the user of the device will request the surface paint of the motor according to the color of the device itself, such as description and communication by means of color number.
It can be found in the actual use process that paints of the same color number produced by different manufacturers will have some color differences, and products of different batches of the same manufacturer will also have some differences. In order to better achieve the consistency of color perception, the standardized motor manufacturers conduct the inspection and control of the paint through the color difference detector, and carry out the necessary comparison and inspection of the processing process.
In order to facilitate the work, the partner can use the color label card agreed in advance for comparison, that is, to determine the comparison benchmark, and then achieve the final consensus through color difference control.

About color difference
Chromatic aberration, also known as chromatic aberration, is a serious defect of lens imaging. Chromatic aberration is simply a difference in color. It occurs when polychromatic light is used as the light source, and monochromatic light does not produce chromatic aberration. The wavelength range of visible light is about 400 to 700 nanometers. Different wavelengths of light have different colors, and their refractive indexes when passing through the lens are also different. In this way, a spot on the object side may form a color spot on the image side. The chromatic aberration generally has position chromatic aberration and magnification chromatic aberration. The positional chromatic aberration makes the image observed at any position, with color spots or halos, which makes the image blurry, and the magnification chromatic aberration makes the image with colored edges.
How to make color difference measurement?
Color difference measurement is to use a special color detection instrument (color difference meter) to measure the color of the surface of two objects, and then compare the color difference of the surface of the two objects, which is the color difference measurement.
Using color-difference instruments for color-difference measurement can not only effectively avoid the subjective error of color detection by human eyes, but also improve the efficiency and accuracy of color detection. Detecting the color difference with the naked eye varies from person to person. Visually detecting the color with the naked eye is easily disturbed by various uncontrollable factors such as external light, human emotions, and perception of color perception. The specific control of color is not so accurate. The color difference meter can quickly and accurately measure the Lab value of the object, and the difference between the two colors can be obtained through analysis. Through long-term observation of the Lab value, we will find that when the difference between the Lab values is greater than 1, our naked eyes can clearly feel the existence of color difference.
In industry, in order to save time and improve production efficiency, a tolerance range is generally set in advance. When performing quality control, when measuring the color difference of a sample, as long as it is within the tolerance range, it is qualified, otherwise it is unqualified. This not only controls the color quality of the product, but also improves efficiency. By using Lab color space, our production control achieves accurate data quantification.
