Kune marudzi akawanda emagetsi emwenje, maitiro avo e spectral akasiyana, saka chinhu chimwe chete munzvimbo dzakasiyana dzechiedza cheradiation, icharatidza mavara akasiyana, uku ndiko kuburitsa kwemavara kwechiedza.
Kazhinji, vanhu vajaira kusiyana kweruvara muchiedza chezuva, saka kana vachienzanisa maratidziro eruvara, vanowanzotora chitubu chemwenje chekugadzira pedyo nemwenje wezuva sechiedza chemazuva ose, uye kana chiedza chiri pedyo nechiedza chemazuva ose, ndipo panobva pakwirira indekisi yeruvara rwayo.
Nzvimbo dzakakodzera kune dzakasiyana mavara ekupa indices. Munzvimbo dzinofanirwa kujekeserwa mavara, musanganiswa wemavara mazhinji emwenje ane spectra akakodzera anogona kushandiswa.
Iko kupihwa kwemavara ezvinyorwa zvekugadzira kunonyanya kuenderana zvakanyanya nekugovera kwekuona kwekwakabva. Magetsi ane chiedza chinoenderera chakafanana nechiedza chezuva uye mwenje weincandescent zvese zvine mavara akanaka anoburitsa. Iyo yakabatana bvunzo ruvara nzira inoshandiswa kuiongorora kumba nekune dzimwe nyika. Iyo yehuwandu indekisi indekisi yekukura kwemavara (CRI), inosanganisira iyo general color development index (Ra) uye yakakosha color development index (Ri). Indekisi yemavara eruzhinji inowanzo shandiswa chete kuongorora indekisi yeruvara yakakosha, inongoshandiswa kuongorora maratidzirwo eruvara rwechiedza chakayerwa kuruvara rweganda remunhu. Kana iyo indekisi yeruvara inoratidzira yemwenje inoyerwa iri pakati pe75 ne100, yakanaka kwazvo; uye pakati pe50 ne75, kazhinji irombo.
Kunyaradzwa kwekushisa kwemavara kune humwe hukama kune chiyero chekuvhenekera. Pachiedza chakadzikira, chiedza chakasununguka iruvara rwetembiricha yeruvara rwakaderera pedyo nemurazvo, pachiedza chakaderera kana chiri pakati nepakati, chiedza chemutambarakede iruvara rwakati kwirei pedyo nekumambakwedza nemasikati, uye pachiedza chepamusoro pane tembiricha yemudenga ine ruvara rwedenga pedyo nemasikati ezuva kana bhuruu. Saka kana uchigadzira nzvimbo yemukati yemamiriro ekunze akasiyana, kupenya kwakakodzera kwemavara kunofanirwa kusarudzwa.
