Ngelixa bayakrokra ngokwam ngayo ekupheleni komdlalo (ngenxa ekukhanyeni) izolo ebusuku, a Kwathi qatha kum - ngebhola ebomvu kunye pitch eluhlaza, ingaba abantu abangaboniyo ngombala obomvu-luhlaza badlale iqakamba ngempumelelo?
Andikwazi ukucinga ukuba kutheni izitya ezinokuthi zenziwe kakubi, kodwa bekwenza nokuganga kungaba nzima kakhulu. Nge emehlweni-screen naziphi na iingxaki kufuneka incitshiswe, kunye ezininzi iintlanzi entsimini babe isibhakabhaka nje umzobo, kodwa khona kuya kubakho amaxesha apho ibhola kufuneka kube nzima ngakumbi ukuba zikhethe. ke, zininzi abadlali kwi eliphezulu kwinqanaba lombala-blind? Kubonakala ukuba le Australia wandibetha kuyo, yaye sele kwenziwe le sihlume nzima ukuba awuphendule lo mbuzo. isiphetho: kumanqanaba uninzi lwabantu umbala-iimfama zimelwe ngokuhambelana inani labo labantu (ngeenxa 10%), kodwa kumanqanaba aphezulu kakhulu kukho phantse akukho bantu umbala-abangaboniyo kwaphela (Bill Ponsford inokuba Kwimeko ongasetyenziswayo kuyo lo mgaqo. Le legend Aussie wadlala 29 test elithelekiseka kwi-avareji 48). Kubonakala ukuba kumanqanaba aphezulu kakhulu ukuba umbala-iimfama sisithintelo ebalulekileyo. Kuwo onke amanqanaba, abadlali ngemibala-nangobumfama bakufumanisa kunzima ukubona ibhola liphela ingca, isalusa ukuphepha phakathi kunye nezikhundla ukuganga olunzulu - abathetheli phawula! Ezinye izifundo lubonise ukuba Abaqhokri imibala-blind azichaphazeleki kakhulu, umzekelo ukuba i-avareji okudlala kunye ibhola emhlophe eyahlukileyo akukho ukusuka avareji babo ibhola ebomvu.
Ngoko ke, kubonakala ukuba ngeli xesha na ukuba kungenzeka ukufumana abadlali abaninzi uvavanyo ngamazwe umbala-blind, xa sele umbala-iimfama kwaye ufuna ukufumana kwiklabhu yasekuhlaleni-veki kwi, hamba uze ubambezeleke! Kananjalo imali iperi Oxy-Suomen iiglasi, leyo kuthiwa ukuphucula Imibala nemifuno!
Mandithathe kwakhona ndithi, kukho iimeko ezininzi ezahlukeneyo eziwela phantsi kwegama ngengubo "bomvu-luhlaza lombala-blind", angala protanopia, deuteranopia, protanomaly, kunye deuteranomaly. Ukuba ucinga ukuba ungafika unayo enye yezi meko ke ndingenalo waxilongwa, nceda thetha nogqirha wakho (phambi okanye emva komdlalo) - siyaqhubeka iwebhusayithi leqakamba hayi ezonyango!
Ibhola epinki ibonakala ingwevu/ebhlowu kumbala obomvu/oluhlaza onqongopheleyo, kuxhomekeke kubukhali bayo. Ndenze ukulinganisa ngesoftware yobumfama bombala apho ibhola yaphantse yanyamalala ngokuchasene nesibhakabhaka esiluhlaza. Ubunzulu beblue nabo buyohluka kwihlabathi jikelele. I-RAF yakuqonda oku ngexesha lemfazwe xa babedinga i-camouflage shades ezahlukeneyo eziluhlaza ngokuxhomekeke apho i-Spitfires yabo yokuhlola yayisebenza khona.. Kwakhona bafumanise ukuba ngorhatya oluthile nakusasa isibhakabhaka sinokuthatha umbala opinki ocacileyo, kwaye kwezi meko ipeyintwe Spitfires pink, ke kunokubakho iingxaki kubadlali beqakamba abanombono oqhelekileyo wokuchola ibhola epinki esibhakabhakeni ekukhanyeni okuthile. Iibhola ezimhlophe zilungile, kwaye tyheli, kodwa hayi orenji ngesizathu esifanayo nebomvu.
