《太平广记·卷二百二十二·相二》
御史中丞尚衡童年时，一次在外面玩耍，脱掉了青绿色的外衣，只穿着一件紫色的衣衫，有一位擅长相面的人看见了，说：这小孩以后，应该也是脱绿穿紫呵。
御史中丞尚衡童幼之时游戏，曾脱其碧衫，唯著紫衫。有善相者见之曰：此儿已后，当以脱碧著紫矣。
Shang Heng, the chief censor of the Court of Censors, was playing outside when he was a child. He took off his green coat and only wore a purple shirt. A person who was good at physiognomy saw him and said: This child should also wear purple after taking off the green.
