What is 'What color do you want' when translated from English to French?

Quelle couleur veux-tu? and Quelle couleur voulez-vous? are French equivalents of the English phrase "What color do you want?" Context makes clear whether one "you" formally (case 2) or informally (example 1) or two or more "you all" (instance 2) suits. The respective pronunciations will be "kel koo-lur vuh-tyoo" and "kel koo-lur voo-ley-zoo" in French.
