A Color Map of the Sun is the fourth studio album by the American electronic music producer Pretty Lights, released on July 2, 2013 by Pretty Lights Music and 8 Minutes 20 Seconds Records. The album is Smith's second double album, as well as his first to be composed entirely from his own original material. Smith's recordings were originally pressed as samples on vinyl and then mixed using software. Purely analog modular synthesis was also used in the making of the album. In describing why he chose this requirement, Smith has stated: "I was trying to think of something that would be a massive challenge for myself and just a really cool project. I wanted to also prove to myself I could do it."
