Karastan Artworks Tango Rectangle 74200-212 Area Rug - 5'x8' Clean, sculptural lines and contrasting color blocks characterize Tango. Tango's color blocks combine with a playfully curvaceous pair of lines to produce a modern flair. Espresso, olive, terra cotta and berry colors make this the moodiest, and perhaps edgiest, of the five Artworks patterns.
