Yeyiphi Imibala Edibanisayo?

Kukho iinkcazo ezininzi zemibala ehambelanayo, kuxhomekeke kwimodeli yombala. Ngeenkcazo ezininzi, imibala ehambelanayo yileyo irhoxisa enye kwenye xa idibanisa okanye idibanisa. Xa imibala isecaleni komnye nomnye, ibonelela ngowona mahluko mkhulu kunokwenzeka. Lo mahluko ukhokelele ekubeni abantu abaninzi babhekisele kwimibala ehambelanayo njengemibala eyahlukileyo. Kukho imibala emininzi ehambelanayo enokubakho, nangona imodeli yombala nganye inombala wayo ophambili ohambelanayo.

Imodeli yeMbala yesiNtu

Ngenkulungwane ye-18, ivili lombala eliqhelekileyo labakho, yaye lisasetyenziswa nanamhlanje. Eli vili lombala libonisa obomvu, tyheli, kunye nobhlowu njengemibala ephambili. Izibini zayo ezincedisanayo zibomvu-luhlaza, zityheli-mfusa, kunye nebhlowu-orenji. Ukudibanisa nayiphi na imibala emibini ephambili kuya kudala umbala ohambelanayo wombala wokuqala oseleyo. Njengomzekelo, ukuxuba obomvu kunye nobhlowu kuya kudala purple ukuncoma tyheli. Ukongeza, ngenxa yokuba imodeli ixhaphake kwipeyinti, isebenzisa umbala othobileyo. Oku kubhekisela kwinto yokuba ipeyinti ithatha ukukhanya, oku kuthetha ukuba ukuxuba yonke imibala emithathu ephambili kunye kuya kubangela umbala omnyama okanye ompunga. Kwiminyaka yakutshanje, izikhokelo zombala ezichaneke ngakumbi zibiza i-magenta, cyan, kunye netyheli njengemibala ephambili.

Imodeli yeRGB

Phakathi kwiminyaka yoo-1800s, abafoti baqala ukuzama izihluzi zemibala eyahlukeneyo yeefoto ezinemibala. Ngenkulungwane ye-20, imodeli yagqitywa, kwaye imodeli yombala we-RGB yaba yinto eqhelekileyo. Igama layo livela kwimibala yayo emithathu ephambili: obomvu, oluhlaza kunye noluhlaza okwesibhakabhaka. Imodeli yeRGB isebenzisa indibaniselwano eyahlukileyo yale mibala mithathu iphambili ukwenza eminye imibala eyahlukeneyo. Ngaphantsi kwemodeli ye-RGB, ukukhanya kwemibala emibini ehambelanayo kubukhulu obupheleleyo kuya kudala ukukhanya okumhlophe. Imibala ehambelanayo yombala kule modeli iluhlaza-magenta, i-red-cyan, kunye ne-blue-yellow.

Ushicilelo lombala

Njengomzobo kunye nemodeli yombala wendabuko, ukuprintwa kombala kuxhomekeke kwimibala ethobileyo ukwenza imibala yayo eyahlukeneyo. Nangona kunjalo, imibala yayo ehambelanayo yahlukile kunaleyo yevili lombala wendabuko. Ukuprintwa kombala kusebenzisa imodeli yombala ye-CMYK yangoku, iyenza imibala yayo ephambili ibe cyan, imagenta, kunye netyheli. Ikwasebenzisa umnyama ukunyusa uluhlu lweethoni ezinokuzenza. Kushicilelo lwemibala, ezona zibini zixhaphakileyo ezihambelanayo zi-magenta-green, yellow-blue, kunye ne-cyan-red. Le modeli ibonelela ngeziphumo ezifanayo njengemodeli yombala we-RGB, kwaye ukongeza omnyama kuvumela imodeli ukuba ibe mnyama imibala.

Inzululwazi yoQeqesho

Abantu abaninzi banokuzibuza ukuba kutheni imibala ehambelanayo ikholisa iliso. Ngokwenzululwazi, yonke into ifika esweni. Amehlo omntu aneentlobo ezininzi zeeseli zephotoreceptor ezinceda ekuboneni umbala. Iindidi ezahlukeneyo zeeseli zinokubona iintlobo ezahlukeneyo zokukhanya ukusuka kumbala wombala. Njengovavanyo, jonga iphepha elibomvu imizuzu emininzi. Xa usugqibile, jonga udonga olumhlophe okanye iphepha elimhlophe. Uya kubona umfanekiso omhlophe omhlophe. Amehlo abona ukukhanya okumhlophe kodwa kubomvu kancinci, okukhokelela kwi-cyan ehambelanayo. Oku kwenzeka ngenxa yokuba ii-photoreceptors ezinoxanduva lokubona umbala obomvu ziyadinwa kwaye ziphulukane nesakhono sazo sokuthumela olo lwazi ebuchotsheni.

Kushushu kwaye Kupholile

Into ebalulekileyo ukuba uyiqaphele kukuba yonke imidibaniso ephambili yemibala ehambelanayo iqukethe umbala ofudumele kunye nombala opholileyo. Ukufudumala kunye nepholileyo ngamagama achaza ngokucacileyo okanye isibindi sombala. Imibala efudumeleyo efana nobomvu kunye notyheli iyaguquka kwaye inesibindi, kodwa imibala epholileyo efana ne-cyan kunye nemfusa ithambile kwaye ithambile. Ngenxa yokuba zihluke ngokuphawulekayo, umbala ofudumeleyo kunye nombala opholileyo uya kuhlala uhluke.

Blue and Orange

Enye yezona zinto zixhaphakileyo zokubhanqa kombala ohambelanayo yiblue-orenji. Amagcisa amaninzi kuyo yonke imbali athembele kule mibala ukuba yongeze umahluko kwimisebenzi yawo. Umdibaniso wombala uye wabaluleka ngakumbi kubazobi ababonisa umdla. Omnye weyona misebenzi imangalisayo kaClaude Monet, Umbono, Ukuphuma kwelanga iqulethe phantse ngokupheleleyo i-shades eluhlaza okwesibhakabhaka kunye ne-orenji. UVincent van Gogh wayesoloko exhomekeke kwimibala ehambelanayo, ngakumbi ukubhanqa kweblue-orenji. Umzobo odumileyo Ubusuku obuneenkwenkwezi Ibonisa inyanga eorenji eneenkwenkwezi eziorenji ngokuchasene nesibhakabhaka sasebusuku esiluhlaza. Nditsho neyakhe Umzobo wakho ibandakanya ubukhulu becala imibala e-orenji kunye nebhlowu.

Ubomvu kunye noBuhlaza

Nangona abantu abaninzi benxulumanisa umbala obomvu-oluhlaza ukubhanqa kunye neKrisimesi, imibala ehambelanayo ivele kwezinye imidiya engeyiyo iholide kangangamakhulu eminyaka. UVan Gogh wasebenzisa obomvu kunye nohlaza kwimisebenzi yakhe emininzi, nangona umzekelo odumileyo kunokwenzeka ICaf yasebusuku Yiyo. UVan Gogh wayekholelwa ukuba obomvu kunye nohlaza babonisa iimvakalelo ezimbi zomntu. Abapeyinti banamhlanje abangakumbi abanjengoPablo Picasso kunye noGeorgia O'Keeffe nabo basebenzise ukubhanqa ngesiphumo esihle. I-Picasso's Inkosikazi Enomnqwazi kunye ne-O'Keeffe Nantoni na hlala iziqwenga ezidumileyo ezibonisa ukomelela kwemibala ehambelanayo.

Mthubi kunye noMsobo

Kwimibala emininzi ehambelanayo, umthubi kunye nomfusa ngokwembali azizange zikwazi ukuthandwa kwezinye iindibaniselwano. Nangona kunjalo, eminye imisebenzi edumileyo yembali isebenzisa imibala. Umzekelo, nangona umthubi kunye nomfusa zingalawuli isiqwenga, iMonet's Iinyibiba zamanzi isebenzisa iingcebiso zemibala kuwo wonke amanzi kunye neentyatyambo ukunika umzobo umbono omangalisayo. URay Spillenger ubizwa ngokufanelekileyo Purple kunye neYellow ngumzekelo ogqibeleleyo wendlela imibala eyahlukileyo intle ngayo kunye.

Ukusetyenziswa kwanamhlanje

Nangoku, imibala ehambelanayo kunye nokuhamba kwayo okwahlukeneyo kwenzeka kuzo zonke iintlobo zemidiya. Ngenxa yembonakalo yazo enomtsalane kunye nokwahlukileyo, imibala ehambelanayo yinxalenye ebalulekileyo yoyilo lobuhle. Iifilimu ezininzi kunye neenkqubo zikamabonwakude zisebenzisa imibala ehambelanayo kwiintengiso zazo. Ibhulowu kunye neorenji, ngakumbi, zixhaphake ngokumangalisayo kuzo zonke iipowusta zemuvi. Ezinye iziqwenga zentengiso ezifana neelogo, imiboniso yokuthengisa, kunye neempawu zonke zixhomekeke kwimibala ehambelanayo.

Izicelo eziSebenzayo

Zininzi izicelo ezisebenzayo ezithatha ithuba lokuchasana kwemibala ehambelanayo. Umzekelo, ngenxa yokuba iblue neorenji yimibala ehambelanayo, iirafti ezininzi zobomi, iivesti zobomi, kunye nezixhobo zokusetyenziswa ngaphantsi kwamanzi ziorenji. Oku kwenzelwa ukuba umbala o-orenji ugqame ngokumangalisayo ngokuchasene namanzi olwandle abhlowu. Ukongeza, nangona iwile ekuthandeni kwiminyaka yakutshanje, itekhnoloji ye-anaglyph 3D ixhomekeke kwimibala ehambelanayo. Iiglasi ze-nostalgic zixhomekeke kwindalo ehambelanayo ye-cyan kunye nebomvu ukuvelisa imifanekiso ye-3D evela kwizikrini.
