By slightly putting the weight on the clarity with regard to the harmony of clarity and muddiness, its color is the softness. By adding three-dimensionality and warmth, we finished it as a refined color with a calmness overall. For the light ink stick, it is a refined red brown purple-type black where a heartwarming warmth can be felt within the brightness and beauty. For the thick ink stick, it is an elegant black with thickness and warmth within a sharpness. It can be used for hanging scrolls in kanji, small number of characters, and kana. Thick to extra light ink sticks can be used. As it gets older, we believe the ink stick calms in color, and its three-dimensionality, sharpness, personality, and features grow stronger. 1993
