Indigo Powder, INCI yitwa Indigofera Tinctoria Leaf Powder, ni ifu nziza iva mu mababi yumye y’ikimera cya indigo Indigofera tinctoria. Ni ibikoresho fatizo bikomoka ku bimera bidafite ibice bikomoka ku nyamaswa. Ikintu cy’ingenzi kiyigize ni indican, ihinduka ibara ry’ubururu rya indigotin nyuma yo gushonga no gushonga iyo ishyizwe mu kirere. Ifu ubwayo igaragaza isura y’icyatsi kibisi ifite impumuro y’ibyatsi by’ibimera. Mu myaka ibihumbi ishize, indigo yakoreshejwe mu gusiga irangi mu myenda hirya no hino muri Aziya no mu Burasirazuba bwo Hagati, none ubu ikunzwe cyane nk’ibikoresho fatizo byo kwisiga bisanzwe mu gusiga irangi ku musatsi.

Nk'umuti usanzwe w'ibara ry'umusatsi, ifu ya indigo ntifungura cyangwa ngo yangize ibice by'umusatsi nk'irangi ry'umusatsi rihoraho. Ishyira ibara ku buso bw'umusatsi. Ubusanzwe ikora neza hamwe na henna (ifu y'amababi ya Lawsonia inermis). Nyuma yo kuvurwa na henna, indigo ishobora kugira amabara menshi y'umukara wijimye kugeza ku mukara kandi igatwikira umusatsi w'imvi neza. Uretse gukora ibara, ifu ya indigo inatanga ibyiza byo kwita ku ruhu rw'umusatsi. Ifite ubushobozi bwo kurwanya udukoko no kurwanya ububyimbirwe, ifasha kugabanya ububabare bwo mu mutwe no kunoza imiterere y'umusatsi, bigatuma umusatsi uba mwiza kandi urabagirana.

Abaguzi benshi bahitamo ifu ya indigo nk'uburyo bwo guhindura ibara ry'umusatsi karemano udafite ammonia, udafite PPD. Kimwe mu bibazo bikunze kubazwa ni igihe ibara ry'umusatsi rishobora kumara ku musatsi. Ibara ry'umusatsi rikomoka kuri Indigo rikoreshwa mu irangi rihoraho ry'ibimera. Iyo rikoreshejwe hakurikijwe uburyo busanzwe bwo gukora ibara rya henna indigo kandi rigafatwa neza nyuma yo kwitabwaho, ibara risanzwe rimara ibyumweru 4-6 mbere yuko ritangira gucika buhoro buhoro. Bitandukanye n'irangi ry'umusatsi rihoraho rikoreshwa mu buryo bwa shimi ricika bitewe n'imirongo igaragara y'imizi, ibara rya indigo ricika buhoro buhoro kandi buhoro buhoro, nta mbibi z'amabara zikomeye ku misatsi. Ibintu byinshi by'ingenzi bigena igihe nyacyo cyo kumara.

Abakoresha bakeneye kwitega irangi ry’ibimera mu buryo bufatika. Bisabwa kongera gukoresha irangi buri byumweru 4-6 kugira ngo ibara ry’umukara wijimye cyangwa umukara wijimye rikomeze kuba ryiza. Gukoresha inshuro nyinshi mu buryo buhoraho bizatuma ibara ry’umusatsi rikomeza kwiyongera kandi rigatuma umusatsi upfuka neza kandi rigakomeza kuramba. Ni ngombwa kwibutsa ko ifu ya indigo ikoreshwa gusa mu kwisiga, isuzuma ry’uruhu ni itegeko mbere yo kubaga irangi ry’umusatsi ku mugaragaro.

Muri iki gihe, mu gihe abaguzi bo ku isi bakomeza gushaka irangi ry’umusatsi ridafite amoniya, ifu ya indigo yabaye imwe mu bikoresho by’umwimerere bikunzwe cyane byo kwisiga. Ihuza ubwenge bwa kera bw’ibimera n’uburyo bugezweho bwo kwisiga, itanga uburyo bwo gusiga irangi karemano butekanye kandi busanzwe.
