Medieval Tokoname ceramic dates from the end of the Heian era to the Kamakura age. Many Jars of Tokoname are covered with a natural glaze. Old Tokoname ceramic fragments were found in archeological digs of kilns which made these jars. Kilns for this analysis were located in Shibayama, Shiike, Dechita, Yariba, Takasaka, and Nagaso in Tokoname area. The analysis procedure is as follows. Ceramic fragments were photographed at the equal lighting condition as much as possible by digital camera. A certain small difference was revised in software of Adobe Lightroom between each. Digital image of fragments was analyzed by "a" channel and "b" channel from L^*a^*b color conversion of Adobe Photoshop. As a result, at the various fragments in Tokoname make little difference of natural glazed fragments color. These colors are limited to the very small range of the frame of L^*a^*b color conversion system. The other time, medieval Tanba ceramic fragments were analyzed by the same method. The range of Tokoname's fragments color is different from the range of Tanba's color clearly. This method is useful for the study of the color of the ceramics of the old times.
