Which source should the color value of "Japanese traditional color" be based on?

There are all kinds of color books in Japan, most of which are self-contained. The so-called Japanese traditional color is not a standard, but a product of various color institutions. I think which one looks good is which one. In addition, I think the share of DIC is very high, and it is better to follow DIC standards.

The general impression is that among the non-irritating colors, the lightness and purity are medium and the tone is full. Give people a soft, restrained and elegant feeling. If different colors can give people different impressions, then the traditional Japanese color must be the cleanest and freshest one.

At the same time, its interaction and design are consistent with the PC version to the greatest extent. In the study of color, the producer named 250 kinds of traditional colors born in traditional Japanese arts and crafts with Chinese characters through poetic imagination such as metaphor and synaesthesia, and also marked the related Japanese pronunciations.
