Indigo Algorithm -Ai no Denshi Kisuuhou- ("Indigo Algorithm"－藍の電思基数法－), also known as "Quantum Mechanics Rainbow II: Indigo Algorithm", is the seventh (sixth of entirely new music) solo album by artist Daisuke Asakura. It is the second in a series of seven albums released by Asakura in 2004, called "Quantum Mechanics Rainbow". Each album revolves around a different color of the rainbow and a different term relating to Quantum Mechanics. This album revolves around the color indigo. The album also contains a re-arrangement of a song originally performed by another, now defunct, band that Daisuke Asakura had produced in the past, The Seeker. It also contains guest vocals by Takatoshi Shindo (Track 5).
