The original coloring materials are remaining at arts and crafts in the 7th century to the 8th century, those coloring materials have been keeping use for ornaments of arts and crafts till the 17-18th century. In documents of the 7-8th century we can find many descriptions about coloring materials, it appears there was limitation to use coloring materials. I try to point out the reason of restriction to use coloring materials that is because of chemical character. There is no research which analyzes quality and characteristic of coloring materials themselves, and insists that chemical changes and chemical reactions cause restriction to use of coloring materials. Even if we analyze optically arts and crafts, we can't point out what coloring materials were used to perfectly. So it's necessary to refer documents which record how the coloring material was used, and in which amount used. In consideration of descriptions of documents and decorations examples of arts and crafts and chemical character of coloring materials, I would like to indicate that the restrictions to use of coloring materials are caused by the compatibility and the aptitude of the coloring material.
