Indigoidine is an organic compound of the azaquinone group. It is a blue pigment produced by some bacterial species that excrete it into the surrounding medium.
== History == Otto Voges researched and described the bacterial species Bacillus indigoferus in 1893, renamed after him to Vogesella indigofera, in Kiel, which continuously discolored the surrounding medium (water) from slightly bluish (24 hours) to royal blue (48 hours).
