Abstract:RGB images are images that are detected, represented and displayed in electronic systems. The color matching method is to perform color recognition on the existing RGB image, record the captured color and generate a variety of color matching schemes to apply to the appearance control of auxiliary objects. Based on the characteristics of RGB and HBS color modes, this paper uses color recognition methods to collect the colors of electronic pictures. The collected color data generates different color schemes according to the color characteristics, matching principles and data extraction models to provide references for electronic system control. According to the experimental comparison effect and application data, using this color matching method to control the related objects in the electronic system, the object quality and work efficiency can be significantly improved. This method has certain practical value in the fields of industrial appearance control, electronic interactive control, virtual reality and game User Interface (UI).
