How do you say What colour is it in French?

"What colour is it?" in French can be translated in a few ways, depending on the context:

Formal:

* Quelle est sa couleur ? (This is the most direct translation and is appropriate for formal situations.)

Informal:

* De quelle couleur est-ce ? (This is a more common way to ask the question in informal situations.)

* C'est de quelle couleur ? (This is another informal option, which literally translates to "It's of what color?")

Note: You can also use "la couleur" instead of "sa couleur" in the formal option if you want to emphasize the colour itself.

For example:

* Quelle est la couleur de ce chat ? (What is the color of this cat?)

* De quelle couleur est cette robe ? (What color is this dress?)
