Mazuva ano marumaru ekugadzira agara kwenguva refu anogona kushandiswa nevanhuwo zvavo, uye kuti chigadzirwa chive chakasimba, zvinodiwawo kuti chive chakasimba. Zvisinei, sezvo aruminiyamu hydroxide, iyo inotora anopfuura 60% yekuwedzera marumaru ekugadzira, hunhu hwayo hunokanganisa zvakananga tekinoroji yekugadzirisa uye hunhu hwechigadzirwa chemarumaru ekugadzira.
Chroma ndeimwe yezviratidzo zvakakosha pakuyera mhando yezvigadzirwa zvealuminium hydroxide. Chromaticity inosanganisira index yekuchena isina ruvara, kupenya kwemavara, hue uye saturation index, mune izvi index, kuchena uye a, b value zvine simba guru pakushandiswa kwechigadzirwa.
Mudzidziso, ruvara izwi rinowanzoreva ruvara neruvara. Asichromatic inoreva mavara machena, matema uye akasiyana-siyana egrey, zvishoma nezvishoma kubva pachena kuenda kugrey rakapfava, grey repakati, grey rakasviba, kusvika dema, rakarongwa munhevedzano, iyo inonzi nhevedzano chena nedema. Kuchinja kubva pachena kuenda kudema munhevedzano chena nedema kunogona kumirirwa nemutsetse wakatwasuka, nechena chakachena kune rumwe rutivi uye dema chakachena kune rumwe rutivi, nemavara egrey anochinja pakati. Chena chakachena ndicho chinhu chakakodzera kuratidzwa zvizere, nepo dema chakachena chiri chinhu chakakodzera chisingaratidzi.
Kuchena kwacho kwakavakirwa pachiyero chechiedza chemagnesium oxide chakajairwa chemhando ye "monochromatic absolute reflection" chebhodhi jena re "standard white board" kusvika pa "specific wavelength", uye chiyero chechiedza che "absolute reflection" che "sample surface" chinoyerwa ne "wavelength" inoenderana, inoratidzwa se "percentage". Iyo "baidu" yebhodhi jena rehari ne "porcelain", zvinoreva kutora "purple white porcelain" sebhodhi jena re "standard reflection" kune chiyero chechiedza che "monochromatic wavelength" chaiyo, inoratidzwa ne "percentage". Muindasitiri ye "aluminium hydroxide" haina kugadza chiyero che "whiteness standards", zvichienderana nemamiriro ekugadzira uye zvinodiwa nevashandisi, ne "ceramic white board" se "standard" yekuona "whiteness" yealuminium hydroxide, uye ne "otomatiki color meter" yekuyera kukosha kwe "whiteness".
Ruvara runoreva mavara machena nematema akatevedzana emavara asingatarisirwi.
Ruvara rune zvinhu zvitatu: kupenya, ruvara, uye kuzara. Pakati pazvo, kupenya kunodaidzawo kupenya, kunopenya nekusiyana kwerima, kuratidzwa kwechiedza chechinhu pamusoro peruvara kwakakwira, kupenya kwakakwira, ziso remunhu rinonzwa rakajeka zvakanyanya. Ruvara runodaidzawo kuti ruvara runosiyanisa rumwe nerumwe. Zvakadai setsvuku, orenji, yero, bhuruu nezvimwewo. Kuzara kunozivikanwawo seruvara, zvinoreva kuchena kweruvara, ruvara runoonekwa rwemhando dzakasiyana dzechiedza che monochromatic ndiro ruvara rwakanyanya kuzara. Zvinhu izvi zvitatu zvinokutendera kuti utsanangure nzvimbo yeruvara chero rupi zvarwo munzvimbo yeruvara.
