A kind of deep blue, one of the seven prismatic colours. 2. <chemistry> A blue dyestuff obtained from several plants belonging to very different genera and orders; as, the woad, Isatis tinctoria, Indigofera tinctoria, I. Anil, Nereum tinctorium, etc. It is a dark blue earthy substance, tasteless and odorless, with a copper-violet luster when rubbed. Indigo does not exist in the plants as such, but is obtained by decomposition of the glycoside indican. Commercial indigo contains the essential colouring principle indigo blue or indigotine, with several other dyes; as, indigo red, indigo brown, etc, and various impurities. Indigo is insoluble in ordinary reagents, with the exception of strong sulphuric acid. <botany> Chinese indigo, the American herb Baptisia tinctoria which yields a poor quality of indigo, as do several other species of the same genus. Having the colour of, pertaining to, or derived from, indigo. <botany> Indigo berry, the gopher snake.
