Sophistication is a warm grey.
It can be described as warm, muted, greyish and dusty.

Sophistication refers to the qualities of refinement, good taste, and wisdom. By contrast, its original use was as a pejorative, derived from sophist, and included the idea of admixture or adulteration. Today, as researched by Faye Hammill, it is common as a measure of refinement—displaying good taste, wisdom and subtlety rather than crudeness, stupidity and vulgarity.
Read on WikipediaSophistication of books is the practice of making a book complete by replacing missing leaves with leaves from another copy. In some cases this is done with the intent to deceive or mislead, modifying and offering books for sale in an attempt to sell them for a higher value. When offered for sale, a book's description should be clear and unambiguous, and indicate exactly and in detail any changes that have been made to the book.
