Yellow Vector – Ki no Taji Gen Shikousei- (Yellow Vector－黄の多次限指向性-), also known as Quantum Mechanics Rainbow V: Yellow Vector, is the tenth solo album from Japanese musician Daisuke Asakura released on November 30, 2004. The album is the fifth in the Quantum Mechanics Rainbow series. The concept of this series is "one album for every rainbow color and a different Quantum Mechanics term". Track 7 is dedicated to D.A.N.K, a boy band Asakura formed in a futile attempt to copy the popularity of Japanese music company Johnny’s Entertainment Company. Tracks 1 and 8 make references to physicistErwin Schrödinger and mathematicianPierre-Simon Laplace, respectively. Track 5 contains guest vocals from Mayumi Fujita, who has performed vocals on several of Asakura’s Quantum Mechanics Rainbow albums.
