玄纁為華夏文化最神聖之色彩，天之色謂之玄，地之色為之纁。
玄色：《說文》：黑而有赤色者為玄。“玄”色較之青、赤、黃、白、黑等五正色尤為尊貴而獨居其上。天之色彩即為玄，為至高無上之色。以玄“象”天，天神尚質，亦即天神尚德。祭服常用玄衣，因玄色內涵天道思想；“以玄擬天”“玄乃天道”。
纁：《周禮·王之吉服》疏：“知玄衣纁裳者：見《易 系辭》：‘黃帝堯舜垂衣裳，概取諸乾坤。’乾為天，其色玄；坤為地，其色黃。但土無正位，托位於南方。(南方)火色赤，赤與黃(合)，即是纁色。”《楚辭·九章·思美人》的文句：“指嶓塚之西隈兮，(寫落日依在西山之況)，與纁黃以為期。”王逸注：“纁黃，蓋黃昏時也。纁，一作曛。” 這樣看來，纁色應該是橙黃色系，但《說文》卻說是“淺絳”；《爾雅·釋器》：“絳”。
