     The evaluation and analysis of color in industrial production is very important. In order to ensure the accuracy of color evaluation, professional color light box and color difference meter are needed. These color detection and analysis instruments can accurately obtain color values and avoid visual observation errors. Large and influential factors, such as printing, cosmetics, textiles, automotive, food and other industries have a wide range of applications.
      The reasons for inaccurate color detection mainly include differences in light source, background difference, direction difference, observer difference, and size. Therefore, it is necessary to maintain specific conditions for observing the appearance color of the product. A color detection device is a device that provides a constant color measurement environment. For example, the standard light source can provide a stable light source and observation angle for color detection. The more accurate instrument of color difference meter can measure and display the data result by directly simulating the human eye.
      Therefore, the use of color detection instruments is a necessary part of the industrial production plant, which can reduce many unnecessary losses, and colleagues can improve the production efficiency of the enterprise.
