Curcumin is the active ingredient of the Indian curry spice turmeric. It is a polyphenol with a molecular formula C21H20O6. Curcumin can exist in at least two tautomeric forms, keto and enol.

Haematoxylin, hematoxylin, Natural Black 1, or C.I. 75290 is extracted from the wood of the logwood tree. When oxidised it forms haematein, a compound with rich blue-purple colour, and is used, together with a suitable mordant (most commonly Fe(III) or Al(III) salts), to stain cell nuclei prior to examination under a microscope. Structures that stain with haematoxylin are called basophilic. ...more on Wikipedia about "Haematoxylin"

Indian Yellow, also called euxanthin or euxanthine, is a transparent yellow pigment used in oil painting. See Pigments. Chemically it is a magnesium euxanthate, a magnesium lake of euxanthic acid. It is a clear, deep and luminescent yellow pigment. Its color is deeper than gamboge but less pure than cadmium yellow. ...more on Wikipedia about "Indian Yellow"

Indigo dye is an important dyestuff with a distinctive blue color (see indigo). The natural dye comes from several species of plant, but nearly all indigo produced today is synthetic. Among other uses, it is used in the production of denim cloth for blue jeans. The form of indigo used in food is called "indigotine", and is listed as FD&C Blue No. 2. ...more on Wikipedia about "Indigo dye"

Kermes (or chermes) in persian language means red insect is the dried bodies of the females of a scale insect ( Kermes ilices, formerly Coccus ilicis), allied to the cochineal insect, and found on several species of oak near the Mediterranean. The insects are round, about the size of a pea, contain coloring matter analogous to carmine, and are used in dyeing. Red dye was created from the kermes insect, and the word crimson is derived from the word kermes. These insects were anciently thought to be of a vegetable nature, and were used in medicine. ...more on Wikipedia about "Kermes"

The Logwood tree (Haematoxylum campechianum) was once an important source of red dye. The tree's scientific name means 'bloodwood' ('haima' being Greek for 'blood' and 'xulon' Greek for wood) from the Campeche region of Mexico's Yucatan Peninsula. The Logwood grows throughout Central America. It led to the founding of the modern nation of Belize, which grew from British logging camps of the 17th century. It is still an important source of haematoxylin, used in histology for staining. ...more on Wikipedia about "Logwood"

Quercitron is a yellow dye obtained from the bark of the Black oak (Quercus velutina), a fine forest tree indigenous in North America. The name is a shortened form of quercicitron, from Latin quercus, oak, and citron, lemon, and was invented by Dr Edward Bancroft (1744-1821), who by act of parliament in 1785 was granted special privileges in regard to the importation and use of the substance. The dyestuff is prepared by grinding the bark in mills after it has been freed from its black epidermal layer, and sifting the product to separate the fibrous matter, the fine yellow powder which remains forming the quercitron of commerce. The ruddy-orange decoction of quercitron contains quercitannic acid, whence its use in tanning, and an active dyeing principle, quercitrin, C21H20O12. The latter substance is a glycoside, and in aqueous solution under the influence of mineral acids it yields quercetin, C15H10O7, which is precipitated, and the pentoside rhamnose. Quercetin is a crystalline powder of a brilliant citron yellow color, entirely insoluble in cold and dissolving only sparingly in hot water, but quite soluble in alcohol. Either by itself or in some form of its glucoside quercitrin, quercetin is found in several vegetable substances, among others in cutch, in Persian berries (Rhamnus catharticus), buckwheat leaves (Fagopyrum esculentum), Zante fustic wood (Rhus cotinus), and in rose petals, &c. Quercitron was first introduced as yellow dye in 1775, but it is principally used in the form of flavin, which is the precipitate thrown down from a boiling decoction of quercitron by sulfuric acid. Chemically, quercetin is a member of a fairly extensive class of natural coloring matters derived from phenyl benzoyl-pyrone or flavone, the constitution of which followed on the researches of St von Kostanecki, A. G. Perkin, Herzig, Goldschmidt and others. Among the related, coloring matters are: chrysin from poplar buds, apigenin from parsley, luteolin from weld and dyers broom, fisetin from young fustic and yellow cypress, galangin from galanga root, and myricetin from Nageia nagi. ...more on Wikipedia about "Quercitron"

Each branch will usually have from one to five flower heads containing 15 to 20 seeds per head.

It makes a poor fabric dye as it is not very lightfast. ...more on Wikipedia about "Turmeric"
