Abstract: A portable color detector comprises a light source for illuminating a surface of an object; and a light detector for capturing reflected light from the surface of the object and generating RGB analog signals based on the captured reflected light. The portable color detector comprises a processing unit for converting the RGB analog signals into RGB data, and transmitting the RGB data to a portable quality inspection terminal. The portable quality inspection terminal comprises a processing unit for processing the RGB data received from the portable quality inspection terminal. Processing the RGB data comprises transmitting the RGB data to a quality control platform. Alternatively, nominal RGB data are received by the quality inspection terminal, and processing the RGB data comprises comparing the RGB data with the nominal RGB data, detecting a color anomaly based on the comparison, and transmitting the color anomaly to a quality control platform.
