Gap and Rehab commissioned five bands to write five songs based on five different colors. Five directors then shot music videos of each song/color. The result is Sound of Color.
Yellow was the color assigned to Marié Digby. The Raveonettes take on the colors Black and White. Dntel, one half of The Postal Service, covers the color Red. The Blakes handle the color of Blue. Swizz Beatz gives his take on Green.
The videos were available online at soundofcolor.com, a link that is no longer available, however they can still be found on various sites, including YouTube.
