《太平广记·卷二百二十二·相二》
将军某乙派人给尚衡送象征权位的红色官服和鱼袋，授给他一个临时的官职。尚衡不肯接受，说：我应该脱绿穿紫，这不是我的衣服。
将军某乙使衡将绯衣鱼袋，差摄一官，衡不肯受曰：吾当脱碧着紫，此非吾衣。
General Mou Yi sent someone to Shang Heng to deliver a red official uniform and fish bag symbolizing authority, and granted him a temporary official position. Shang Heng refused to accept it, saying: I should wear purple instead of green. This is not my clothing.
