A color identifying device includes an emitter for supplying light to throw on a tested object, an amorphous photosensor, an amplifier, an ADC and a microprocessor. The emitter is formed with a LED producing three original colors or with three separate LED producing separate colors of red, green and blue. The photosensor receives the reflected light from the object and sends signals of three colors to the amplifier which amplifies the signals and sends them to the ADC. Then the ADC converts the analog signals into digital signals to be sent to the microprocessor which calculates the digital signals by a program identifying the colors of the object accurately.
