Kule mihla imabula yokwenziwa sele ihlala ixesha elide kubantu abaqhelekileyo, umgangatho wemveliso nawo uyimfuneko engqongqo ngakumbi nangakumbi. Nangona kunjalo, njenge-aluminium hydroxide, ethatha ngaphezulu kwe-60% yokongeza imabula yokwenziwa, umgangatho wayo uchaphazela ngokuthe ngqo iteknoloji yokucubungula kunye nomgangatho wemveliso yemabula yokwenziwa.
I-Chroma yenye yezona mpawu zibalulekileyo zokulinganisa umgangatho weemveliso ze-aluminium hydroxide. I-Chromaticity ibandakanya i-non-color series whiteness index, i-color series lightness, i-hue kunye ne-saturation index, kwezi mpawu, ubumhlophe kunye nexabiso le-a, b zinefuthe elikhulu ekusetyenzisweni kwemveliso.
Kwithiyori, umbala ligama eliqhelekileyo lombala nombala. I-Anachromatic ibhekisa kumhlophe, omnyama kunye neendidi ezahlukeneyo zemibala engwevu, kancinci kancinci ukusuka kumhlophe ukuya kungwevu olukhanyayo, ngwevu ephakathi, ngwevu emnyama, kude kube mnyama, zihlelwe ngothotho, olubizwa ngokuba luluhlu olumhlophe nomnyama. Utshintsho ukusuka kumhlophe ukuya kumnyama kuthotho olumhlophe nomnyama lunokumelwa ngumgca othe tye, onomhlophe omsulwa kwelinye icala kunye nomnyama omsulwa kwelinye, kunye neendidi zenguqu zegrey embindini. Umhlophe omsulwa yinto efanelekileyo ebonakalisa ngokupheleleyo, ngelixa umnyama omsulwa yinto efanelekileyo engabonakaliyo.
Ubumhlophe busekelwe kwi-monochromatic absolute reflection ratio yebhodi emhlophe eqhelekileyo ye-magnesium oxide ukuya kwi-wavelength ethile, kwaye i-absolute reflection ratio yomphezulu wesampuli ilinganiswa yi-wavelength ehambelanayo, echazwe njengepesenti. I-baidu yebhodi emhlophe ye-porcelain kunye ne-porcelain, kukubonisa ukuthatha i-porcelain emhlophe ecocekileyo kunye ne-porcelain njengebhodi emhlophe eqhelekileyo kwi-absolute reflection ratio yokukhanya kwe-monochromatic ye-wavelength ethile, echazwe ngepesenti. Kwishishini le-aluminium hydroxide alikamiselwanga ukumisela imigangatho yobumhlophe, ngokwemeko yemveliso kunye neemfuno zomsebenzisi, kunye nebhodi emhlophe ye-ceramic njengomgangatho wokumisela ubumhlophe be-aluminium hydroxide, kunye nemitha yombala epheleleyo ezenzekelayo yokulinganisa ixabiso lobumhlophe.
Umbala ubhekisa kuluhlu lwemibala engalindelekanga emhlophe nemnyama.
Umbala uneempawu ezintathu: ukukhanya, umbala, kunye nokugcwala. Phakathi kwazo, ukukhanya kukwabiza ukukhanya, kukhanya ngomahluko omnyama, ukukhanya kombala womphezulu wento kuphezulu, ukukhanya kuphezulu, iliso lomntu livakala likhanya ngakumbi. Ithoni ibiza umbala kwakhona, luphawu lokuba umbala wahlula omnye komnye. Njengobomvu, orenji, otyheli, oluhlaza okwesibhakabhaka njalo njalo. Ukugcwala okwaziwa ngokuba ngumbala, kubhekisa kubunyulu bombala, ububanzi obubonakalayo bokukhanya okucacileyo kombala ngowona mbala ugcwele kakhulu. Ezi mpawu zintathu zikuvumela ukuba uchaze indawo yombala kwindawo yombala.
