Jaipur pink or Sappan wood natural dye extract is produced by solvent extraction method. Sappan wood is known as Indian redwood, or also called as the heartwood of Caesalpinia trees. The heartwood contains different water soluble flavonoids namely, brazilin, protosappanin and haematoxylin. Brazilin is the main flavonoid constituent found in the heartwood, which is well known as the natural red color dye for staining cotton, silk and wool. Under natural condition it mostly grows in hilly areas. The Brazilin gives red pigment to fabrics. In extraction process of Brazilin, the wood is first crushed into powder form and then the powdered bark is boiled with water at high temperature for about 40-45 minute. Then it is filtered and treated with different mordents to give a varied range of strong red dyes, ranging from deep crimsons to pinks.

African marigold [Tagetes erecta L.], a major source of carotenoids and Lutin, is grown as a cut flower and a garden flower, in addition to being grown for its medicinal values. Marigold flowers [Tagetes ], which are yellow to orange red in colour, are a rich source of lutein, a carotenoid pigment. Nowadays, Lutein is becoming an increasingly popular active ingredient used in the Food Industry and Textile coloration.This pigment has acquired greater significance because of its excellent colour value. Although marigold flower extract has been used in veterinary feeds, the potential use of marigold as a natural textile colorant has not been exploited to its full extent. This is due to the lack of information on its safety, stability, and compatibility in textile coloration. The dye potential of the extract was evaluated by dyeing using the flower, in 100 % cotton and silk fabrics under normal dyeing conditions. And it gives good strength and fastness of colour on cotton, silk and yarn.

Candy orange is a natural dye extract produced from seeds of Bixa orellana or annatto tree. Annatto is obtained from the outer layer of the seeds of the tropical tree Bixaorellana L. The principle pigment in annatto, namelybixin, is a carotenoid, which is contained in the resinous coating surrounding the seed itself. Processing may alternatively involve aqueous alkaline hydrolysis with simultaneous production ofnorbixin. Traditionally, water or vegetable oil is used as a suspending agent, although solvent extraction is now also employed to produce more purified annatto extracts. The unmordented cotton gives dull shades but using proper mordant, the colour & brightness of the colouring cloth is increased and offers beautiful orange. The colourful dye extracted from bixa is non- carcinogenic. From Literature, it is seen that due to its non-toxic nature, dye is extensively used in dairy-industry for colouring butter, ghee, cheese, margarine, ice cream, chocolate, meats, cereals, confectionary, spices etc.
