Noma kukhathaza nje ukukhononda ngazibonela ngokwami mayelana ekupheleni play (ngenxa yokuthi bese kumnyama) izolo ebusuku, kungazelelwe umcabango lafika kimi - nge ibhola elibomvu futhi pitch oluhlaza, can red-green colour-blind people play cricket successfully?
Angikwazi ukucabanga ukuthi kungani abaphosayo bezokhishwa kabi kakhulu, kepha ukushaya nokufaka enkundleni kungaba nzima kakhulu. Ngesikrini sokubona noma yibuphi ubunzima kufanele bancishiswe, futhi ukubanjwa okuningi enkundleni kunesibhakabhaka njengesizinda sangemuva, kepha kusazoba nezikhathi lapho ibhola kufanele kube nzima kakhulu ukulikhetha. Ngakho-ke, baningi abadlali abasezingeni eliphakeme kakhulu abangaboni? Kubonakala sengathi abase-Australia banakho ungishaye kuso, futhi sengivele ngenze okuxhunyelelwe kanzima ukunikeza impendulo kulo mbuzo. Isiphetho: emazingeni amaningi abantu abangaboni imibala baboniswa ngokuhambisana nenombolo yabo kubantu (azungeze 10%), kepha emazingeni aphakeme kakhulu akukho bantu abangaboni kahle nhlobo (UBill Ponsford angahle abe ngumthetho. Le nganekwane yase-Aussie yadlala 29 test okufanayo ngesilinganiso se- 48). Kubukeka sengathi emazingeni aphakeme kakhulu ukungaboni umbala kuyisithiyo esikhulu. Kuwo wonke amazinga, Abadlali abanobumpumputhe bebala bakuthola kunzima ukubona ibhola linqamula otshanini futhi bathambekele ekugwemeni izikhundla eziphakathi nendawo nokujula - okaputeni bayabona! Olunye ucwaningo lukhombisile ukuthi abashayayo abangaboni imibala abathinteki kakhulu, isibonelo ukudlala ngokulingene nebhola elimhlophe akuhlukile kunesilinganiso sabo nebhola elibomvu.
Ngakho, kubonakala sengathi ngenkathi singeke sikwazi ukuthola abadlali abaningi bokuhlola abangaboni imibala, uma ungaboni kahle futhi ufuna ukwehlela ekilabhini lendawo ngempelasonto, hamba babhajwe! Ungatshala futhi imali ngababili Oxy-Iso izibuko, okusobala ukuthi kuthuthukisa ubomvu nemifino!
I kumelwe futhi athi, kunezimo ezahlukahlukene ezawela ngaphansi kwegama lengubo "red-green color-blind", okuyi-protanopia, deuteranopia, pranomaly, futhi deuteranomaly. Uma ucabanga ukuthi ungaba nesinye salezi zimo kodwa ungatholakali, ngicela ukhulume nodokotela wakho (ngaphambi noma ngemuva komdlalo) - siyiwebhusayithi yekhilikithi hhayi eyezokwelapha!
The pink ball appears grey/blue in red/green deficient vision, depending on its severity. I did a simulation with colour blindness software where the ball almost disappeared against a blue sky. The depth of blue also varies throughout the world. The RAF realised this during the war when they needed different blue camouflage shades depending where their reconnaissance Spitfires were operating. They also found that in certain evening and morning light the sky can take on a distinct pink tinge, and in these circumstances painted the Spitfires pink, so there could be problems for cricketers with normal vision picking up a pink ball in the sky in certain light. White balls are OK, and yellow, but not orange for same reason as red.
