Is Induline vegan?

Induline is a synthetic dye producing blue, bluish-red, or black shades, consisting of a mixture of several intensely coloured species based mainly on substituted phenazines. It was one of the first synthetic dyes, discovered in 1863 by J. Dale and Heinrich Caro. Although induline itself is no longer in commercial use, the related dye nigrosin is still produced.
