Litmus, indigo and anilin blue are harmless blue colors, while the chlorophilin or the green coloring matter of leaves is a harmless green; anilin greens might also be used. The idea that anilin colors are poisonous is erroneous. It is true that the anilin oil itself (a colorless fluid from which the anilin colors are made) is a poison; but the antidote is to add something to change it into an anilin color, when it becomes comparatively harmless. The anilin colors are also so very powerful a coloring material that only a very minute quantity is needed to color very large amounts of candy, so that even if somewhat poisonous or injurious, it would be necessary to consume several hundred pounds of candy at once in order to produce any poisonous effects of the coloring matter.
