The purpose of this study is to examine the colour rendering property of full colour RGB LED lighting. The problem of the conventional CIE CRI method is considered and new models are suggested for the new lighting source. Each of the models was evaluated with visual experiment results obtained by the white light matching experiment. The suggested model is based on the CIE CRI method but replaces the colour space model by CIELAB, colour difference model by CIEDE2000, and chromatic adaptation model by CAT02.
