藍紫色, also mistakenly known as 愛紫色 (Ai Murasaki Iro), is one of the three songs by Dir En Grey that were never properly released and only performed live in their indies era from 1997 to 1998. The other two are 刹那 and 新曲2.
The song had its debut as 新曲5 (Shinkyoku 5) ("New Song 5") on August 7, 1997. It was also mentioned in FOOL'S MATE #198 (April 1998), where Kyo explained that 新曲2 and 新曲5 were not finished yet and had yet to receive proper names. On May 5, 1998, when the song was performed as 藍紫色 for the first time, Kyo also announced it as such. The official website confirms that the song was played as late as November 2, 1998. This was also the last performance of the song, there are ten confirmed performances in total.
- A live report from Dir En Grey's indies days lists this song as ランシ色 (Ranshishoku).
