Mu mateka yose, abantu bagiye bakoresha ibiti bya cakao mubikorwa bitandukanye. Ntabwo gusa iki giti cyumuhondo gishobora gukoreshwa mubikoresho cyangwa mubishushanyo, ariko bifite n'ubushobozi bwo kuvomairangi ry'umuhondo. Suka gusa amashami ya cotinus mumazi hanyuma ubiteke, kandi umuntu arashobora kureba amazi gahoro gahoro gahinduka ibara ry'umuhondo. Ihinduka ribaho bitewe na flavonol glycoside muri cotinus, ikora nk'irangi ry'ibimera bisanzwe.
Irangi risanzwe ryakuwe mu bimera rimaze igihe kinini rikoreshwa mu gusiga irangi. Inzira ikubiyemo gukoresha pigment igaragara mubice bitandukanye byigihingwa, nkimizi, amababi cyangwa ibishishwa. Cotinus coggygria, ikunze kwitwa igiti cyumwotsi, irazwi nkisoko yisiga irangi ryumuhondo ukize.
Gukuramo irangi ry'umuhondo muri cotinus, amashami yacyo agomba kubanza gukusanywa. Ibi birashobora kuboneka mugukata cyangwa gushaka amashami yaguye. Nyuma yo gukusanya, amashami yibizwa mumazi hanyuma agateka mugihe kitari gito. Ubushyuhe butera flavonol glycoside muri cotinus kurekura imiterere yabyo irangi mumazi.
Mugihe cyo guteka, amazi ahindura buhoro buhoro ibara, yigana ibara ryumuhondo ryerurutse ryibiti ubwabyo. Ihinduka nigisubizo cya flavonol glycoside yinjiza irangi ryabo mumazi. Igihe kirekire amashami yatetse, niko ibara ry'umuhondo riba ryinshi, bikongerera imbaraga irangi.
Irangi rimaze gukurwa muri cotinusi, rirashobora gukoreshwa mu gusiga irangi ibikoresho bitandukanye, harimo ipamba, ubudodo, ndetse nubwoya. Ukurikije ibara ryifuzwa, shyira umwenda muri make cyangwa umwanya muremure mugisubizo cyamabara. Ibi bituma pigment yinjira muri fibre, bikavamo imyenda irangi neza.
Gukoresha amarangi karemano nka cotinusi byarushijeho kwitabwaho mumyaka yashize kuko abantu benshi bashakisha ibikorwa birambye kandi bitangiza ibidukikije. Iri vugurura ntabwo ryagaruye gusa uburyo bwo gusiga amarangi gakondo ahubwo ryazanye ikoranabuhanga rishya nubufatanye hagati yabahanzi b’imyenda n’ibidukikije.
Cotinus ifite byinshi ikoresha muburyo bwimbaho ndetse no gusiga irangi, byerekana akamaro ko kubungabunga no gukoresha umutungo kamere. Mugutahura ubushobozi bwibimera nka cotinusi, turashobora gukomeza guhinga ejo hazaza harambye hishimira ubwiza nakamaro ka kamere.
Muri iki gihe, abantu bakunda amarangi ya gicuti adasanzwe. Uwitekaumuhondo utaziguye 86irashobora gukoreshwa muburyo bwo kutizera. Bazwiho amabara meza kandi yihuse iyo akoreshejwe muburyo butandukanye.
