A color cognition system which can be used for automated inspection systems, automated navigation systems or color education systems is developed in this research. The weighted CIELAB(Commission International do l`Eclairage L*a*b*) color-difference formula is designed to be used for the cognition system on the very first stage of this research. And then an experimental system is constructed to examine the performance of the suggested color cognition model. The suggested model performed excellent cognition rate of 96% at the experiments.
