With the advancement of technology things are becoming simple and easier for us. Color measurement is important for a very wide range of industrial applications including paint, paper, printing, photography, textiles, and plastics. A simple smart hardware embedded into a small lightweight device used for color recognition, which has limited area of equipment. The integrated photodiode with transimpedance amplifier converts the color into voltage. The photodiode output voltage is applied to Microcontroller using analog to digital converter, output is displayed on the liquid crystal display. The microcontroller program controls the ADC and LCD. A simple, precise and inexpensive Microcontroller P89C51RD2 based Instrument set up has been designed, developed to find the Color. Hardware and software are developed for color recognition.
