Colors make language more alive, and in English, idioms with red are some of the most expressive phrases you will ever hear. From anger and warning signs to celebration and success, the color red appears in conversations almost every day. I still remember when my manager said, “This is a red flag,” and I actually looked for a physical flag in the office! Later I learned he meant a warning sign, not a real object. That moment showed me how important idioms are for understanding real English.
