"De Colores" is a classic song, but, frankly, after many years of parenthood, I'm more than willing to call for a personal moratorium on that lovely tune. I'm ready for other songs celebrating in Spanish the many different colors around the world.
I do kinda like this song from Andrés Salguero from his forthcoming debut kids' album ¡Uno, Dos, Tres con Andrés! --it's called "Los Colores" (natch), and it's a gentle folk song pointing out the colors of the world around us. The animation from Santiago Germano is an excellent match, and I think a lot of preschoolers will enjoy the brief animated trip.
