Called also indigo bunting.
Indigo blue.
(a) The essential coloring material of commercial indigo,
from which it is obtained as a dark blue earthy powder,
with a reddish luster, C16H10N2O2, which may be
crystallized by sublimation. Indigo blue is also made
from artificial amido cinnamic acid, and from artificial
isatine; and these methods are of great commercial
importance. Called also indigotin.
(b) A dark, dull blue color like the indigo of commerce.
Indigo brown (Chem.), a brown resinous substance found in
crude indigo.
Indigo copper (Min.), covellite.
Indigo green, a green obtained from indigo.
Indigo plant (Bot.), a leguminous plant of several species
(genus Indigofera), from which indigo is prepared. The
different varieties are natives of Asia, Africa, and
America. Several species are cultivated, of which the most
important are the Indigofera tinctoria, or {common
indigo plant}, the Indigofera Anil, a larger species,
and the Indigofera disperma.
Indigo purple, a purple obtained from indigo.
Indigo red, a dyestuff, isomeric with indigo blue, obtained
from crude indigo as a dark brown amorphous powder.
Indigo snake (Zool.), the gopher snake.

[1913 Webster]
1. A kind of deep blue, one of the seven prismatic colors.
[1913 Webster]
2. (Chem.) A blue dyestuff obtained from several plants
belonging to very different genera and orders, such as,
the woad, Isatis tinctoria (family Cruciferae),
Indigofera suffroticosa, Indigofera tinctoria (family
Leguminosae), Indigofera Anil, Nereum tinctorium,
Polygonum tinctorium Ait. (family Polygonaceae), etc.;
called also natural indigo. 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.
[1913 Webster]
Note: Commercial indigo contains the essential coloring
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.
[1913 Webster]
Chinese indigo (Bot.), Isatis indigotica, a kind of woad.
Wild indigo (Bot.), the American herb Baptisia tinctoria
which yields a poor quality of indigo, as do several other
