Ibikoresho bya okiside ya fer bitanga pigment zidafite ubumara, butavamo amaraso, bwihanganira ikirere, kandi bworoheje.Okiside ya fer isanzwe irimo uruvange rumwe cyangwa byinshi bya ferrous cyangwa ferric oxyde, hamwe numwanda, nka manganese, ibumba, cyangwa ibinyabuzima.Okiside ya sintetike irashobora gukorwa muburyo butandukanye, harimo kubora ubushyuhe bwumunyu wicyuma, nka sulfate ferrous, kugirango bitange umutuku;imvura yo kubyara umuhondo, umutuku, umukara, n'umukara (urugero, inzira ya Penniman-Zoph);no kugabanya ibinyabuzima byifashishwa nicyuma (urugero, nitrobenzene yagabanutse kuri aniline imbere yimiti yihariye) kugirango itange umuhondo numwirabura.Umutuku urashobora kubyara kubara ibara ry'umuhondo cyangwa umukara.

Zifite imbaraga zo gushushanya imbaraga kandi zidasobanutse kurusha andi mabara kuburyo akenshi ashobora gukoreshwa ku kigero cyo hasi ugereranije na pigment naturel.
