- n. A substance obtained in the form of blue powder from leguminous plants of the genus Indigofera, and used as a blue dye. See indigoplant. Indigo does not exist ready-formed in the indigo-plant, but is produced by the decomposition of a glucoside called
indican. The plant is bruised and fermented in vats of water, depositing a blue substance, which is collected and dried in the form of the cubic cakes seen in commerce. In this state indigo has an intensely blue color and an earthy fracture, the kind most esteemed being that which, when rubbed by a hard body, assumes a fine copper-red polish. The indigo of commerce, besides indigo blue, consists of indigo red, indigo brown, and some earthy glutinous matters. Also called Indian blue.
- n. The violet-blue color of the spectrum, extending, according to Helmholtz, from G two thirds of the way to F in the prismatic spectrum. The name was introduced by Newton, but has lately been discarded by the best writers.
- n. An American leguminous plant, Baptisia australis. See Baptisia. Also called blue false indigo and wild indigo.
- n. Same as Japanese indigo.
- n. In Australia, any plant of the genus Swainsona of the bean family, especially S. galegifolia. See Swainsona.
- n. A purplish-blue colour
- n. An indigo-colored dye obtained from certain plants (the indigo plant or woad), or a similar synthetic dye.

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.

“I never heard the term indigo child until I read this article, but there it was in the New York Times on Thursday, and then last night at the video store I saw this--clearly some kind of confluence, at least for me.”
“He told the reporter he hates labels..doesnt like the term indigo and felt the parents need the help not the kids.”
“Newton said it had 7, so most say 7, but many people drop indigo from the list, since humans are generally very poor at differentiating indigo from blue/violet.”
“Dyed in indigo, it was sold near the Dongarii Fort near Bombay.”
“The replacement of woad with indigo is an example of the (literal) intertwining of local and imported coloring sources.”
“Processes to decompose plant matter through chemical or physical techniques had models, for both preparation and results, in indigo and woad. reference Heating, or the addition of fermenting agents, shortened preparation time and ensured that the greatest quantity of color was extracted.”
“His model for discussion, indigo, is based on Saxon blue rather than on a traditional vat as it was in the earlier presentation. reference This is especially important because de la Follie developed several new dyeing processes that employed oil of vitriol — a critical component of the Saxon blue vat.”
“For use as a coloring material, the indigo is placed into an alkaline solution, which again turns it green.”
“The first of these changes was the development of the copperas vat, used in England in the 1730s for solid coloring of cloths as well as the creation of resist patterns. 10 In this process, prepared indigo is added to a mixture of copperas (ferrous sulfate) with lime and potash.”
