What does “diventare rosso” mean in Italian?

In Italian, blushing is described as turning a color: diventare rosso means “to become red.” Diventare is the everyday verb for becoming or turning into something, and rosso is “red,” so the whole phrase paints the picture of a face going red from shyness or embarrassment. It’s plain, standard Italian you’ll hear anywhere. There’s also a one-word version, arrossire, but the color phrase is friendlier and easier to build from.

The exact spoken line is “giulio coniglio è timido e diventa rosso” — the shy rabbit “becomes red” when the dancer hare smiles at him. Diventare (“to become”) is a building block: diventare grande (to grow up), diventare famoso (to become famous), and later sono diventati amici in the same clip (“they became friends”). Pair it with other colors for feelings: diventare bianco come un lenzuolo, “to go white as a sheet,” for fear or shock. The tidy single-word equivalent, arrossire, comes straight from rosso plus the verb ending, but diventare rosso spells it out and is just as natural in conversation.
