Xinjiang soft jade comes in white, greenish-blue, yellow, black, and green as its base colors, thus categorizing it into white jade, greenish-blue jade, yellow jade, black jade, and green jade. There are color differences between the base-colored jades, and these color differences can also be used to distinguish the quality of the texture.

However, their degrees of whiteness vary; some have a bluish tint, some a greenish tint, and others a grayish tint. Therefore, within the industry, descriptive terms are often used, such as "bluish-white," "grayish-white," etc. Some other terms include "pear blossom white," "ivory white," "fish belly white," "coarse rice white," and "chicken...".
