Ponerse rojo.

सांस्कृतिक पृष्ठभूमि

In Spain, 'ponerse como un tomate' is a very common, slightly humorous way to say someone is embarrassed. Mexicans often use 'ponerse colorado' as a softer, more traditional alternative to 'rojo'. In Argentina, the focus is often on the intensity of the emotion, so 'ponerse rojo' is used for both extreme anger and extreme shame. Colombians might use the phrase to describe someone who is shy in a romantic context.
