A children’s book has the following sentence: “When I’m jealous, colour me green”. It looks like that in the west jealous people change their colour from head to toe. Compared with the westerners, Chinese people seem calmer. The only indicator for their jealousy is the change of their eye colour. However, their eyes turn into red instead of green. It can be said in Chinese that somebody is 眼红yǎnhóng.
