<note>&hand; Commercial indigo contains the essential coloring principle <i>indigo blue</i> or <i>indigotine</i>, with several other dyes; as, <i>indigo red</i>, <i>indigo brown</i>, etc., and various impurities. Indigo is insoluble in ordinary reagents, with the exception of strong sulphuric acid.</note>
