A horse of a different color is a different matter entirely. For example, you and your friend might be talking about how to make more money. Your friend suggests investing in the stock market. You mention betting at the race track. "Gambling!" your friend says, "That's a horse of a different color." In other words, it's a different way of thinking about the same topic.__________________________A horse of a different color 意思是完全是另一回事. 例如,你和你的朋友可能正在讨论如何赚更多钱. 你朋友建议投资于股市.你提出投注于赛马. 你的朋友说,"那是赌博,这完全是另一回事."换句话说,这是就同一主题完全不同的思考方式._________________________
