子張進，舉手而問曰：「師聞賁者吉卦，而嘆之乎？
“I am drawn to that which retains its essential, unaltered hue; white should be pure white and black, pure black.
」孔子曰：「賁非正色也，是以嘆之。
What good resides in the hexagram bi?
吾思夫質素，白當正白，黑當正黑。
I have also heard that no designs are added to cinnabar and lacquer, that white jade is never carved, and that precious pearls are never painted.
夫質又何也。

吾亦聞之：丹漆不文，白玉不雕，寶珠不飾，何也？
質有餘者，不受飾也。」
It is because the essential stuff of these objects is so manifest as to reject all decoration.” On the Real Sources of Good Fortune
