Cách sử dụng
The expression "your true colours" means to reveal or show one's real or genuine character, particularly when it comes to negative traits that someone has been hiding. It can be used in situations where someone's behavior or actions betray their true intentions or personality. For example, if someone pretends to be kind but then acts cruelly, someone might say "you have shown your true colours." It can also be used as a warning to be cautious about trusting someone, asking others to "watch out for their true colours."
