ʻO ka pigment hao ʻokikene kahi ʻano pigment me ka maikaʻi o ka hoʻolaha ʻana, ke kūpaʻa maikaʻi loa i ka mālamalama, a me ke kūpaʻa i ka wā. ʻO nā pigment hao ʻokikene e pili nui ana i ʻehā ʻano o nā pigment kala: ʻulaʻula hao ʻokikene, melemele hao, ʻeleʻele hao, a me ka ʻeleʻele hao, me ka hao ʻokikene ma ke ʻano he mea kumu. I waena o lākou, ʻo ka hao ʻokikene ʻulaʻula ka pigment nui (e helu ana ma kahi o 50% o nā pigment hao ʻokikene), a ʻo ka mika hao ʻokikene i hoʻohana ʻia ma ke ʻano he pigment anti-rust a me ka magnetic hao ʻokikene i hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa magnetic e pili ana hoʻi i ka māhele o nā pigment hao ʻokikene. ʻO ka hao ʻokikene ka lua o ka pigment inorganic nui loa ma hope o ka titanium dioxide a ʻo ia hoʻi ka pigment inorganic kala nui loa. ʻOi aku ma mua o 70% o nā pigment hao ʻokikene i hoʻopau ʻia i hoʻomākaukau ʻia e nā ʻano hana synthesis kemika, i ʻike ʻia ʻo synthetic iron oxide. Hoʻohana nui ʻia ka synthetic iron oxide i nā mea kūkulu hale, nā uhi, nā plastics, nā mea uila, ka paka, ka lāʻau lapaʻau, ka rubber, nā keramika, nā ʻīnika, nā mea magnetic, ka hana pepa, a me nā kahua ʻē aʻe ma muli o kona maʻemaʻe synthesis kiʻekiʻe, ka nui o nā ʻāpana like, ka chromatography ākea, nā kala he nui, ke kumukūʻai haʻahaʻa, a me nā waiwai ʻawaʻawa ʻole, a me nā waiwai kala a me nā noi maikaʻi loa, a me nā waiwai omo UV.
