Indlela yokufunda iziphumo zakho

  • Indawo okuluhlaza okwesibhakabhaka kuqala kuyo kuwe: i-hue apho iimpendulo zakho zitshintsha khona ukusuka ku"luhlaza" ukuya ku"luhlaza okwesibhakabhaka". I-hue yi-engile yombala kwisangqa semibala; sisebenzisa isithuba sombala se-OKLCH, apho amanyathelo alinganayo e-hue abonakala ngathi ahluke ngokulinganayo. Kwisikali sethu, okuluhlaza kukufutshane ne-140° kwaye okuluhlaza okwesibhakabhaka kukufutshane ne-250°.
  • Imibala emithathu eboniswayo: umbala oluhlaza kancinci kunomda wakho, umbala womda ngokwawo, nombala ozuba kancinci. Umhlobo usenokubiza lo uphakathi ngegama elahlukileyo.
  • Amanqaku empazamo: abonisa ukuba imibala ekwimiqolo yakho ibikude kangakanani kulandelelwano oluchanekileyo. Umbala ngamnye ufumana amanqaku ngokomahluko phakathi kwawo nemibala emibini esecaleni kwawo, kuthatyathwe u-2; ngoko umqolo ocwangciswe ngokugqibeleleyo ufumana u-0. Amanqaku asezantsi angcono.
  • Isangqa: sibonisa yonke imibala yesangqa se-hue ngombala wayo. Incopho ende ithetha ukudideka okukhulu kuloo hue; "ezona zididayo" libonisa indawo enokudideka okukhulu.

Umda wakho awunampendulo ichanekileyo okanye engachanekanga. Amanqaku empazamo wona anayo: u-0 uthetha ukuba kugqibelele. Akukho nanye kwezi sisiphumo sonyango.

Ngaba oluhlaza okwesibhakabhaka lwam luyafana nolwakho?

Abantu babeka umda phakathi kokuluhlaza nokuluhlaza okwesibhakabhaka kwiindawo ezahlukeneyo. Kuphando lwee-hue "ezizodwa", ukhetho lwabantu lombala ococekileyo oluhlaza noluhlaza okwesibhakabhaka lwahluka kakhulu kangangokuba into eluhlaza okwesibhakabhaka komnye umntu inokuba luhlaza komnye [1]. Iilwimi nazo ziyahluka: kuvavanyo lweelwimi eziyi-120, ezingama-68 zisebenzisa igama elinye ukuchaza okuluhlaza nokuluhlaza okwesibhakabhaka [2]. Ngoko umda womhlobo wakho unokwahluka kowakho.

Iinyani ezikhawulezayo

  • Ukungaboni imibala ngendlela eqhelekileyo: malunga ne-8% yamadoda ne-0.4% yabasetyhini abanemvelaphi yaseYurophu banengxaki yokwahlula okubomvu nokuluhlaza, njengamadoda ayi-4 ukuya kwi-6.5% anemvelaphi yaseTshayina neyaseJapan [3]. Eli phepha aliluvavanyi olo phazamiseko.
  • Amagama nemibala: IsiRashiya sinamagama asisiseko ahlukeneyo aluhlaza okwesibhakabhaka okhanyayo namnyama. Kolunye uphando oluncinane, abantu abathetha isiRashiya bahlula imibala emibini eluhlaza okwesibhakabhaka ngokukhawuleza xa yayikwicala ngalinye lalo mda; abantu abathetha isiNgesi abazange babonise loo mahluko [4].
  • Uvavanyo oluqhelekileyo lokuhlela imibala: uvavanyo lwe-Farnsworth–Munsell 100-hue, olusetyenziswa eziklinikhi, luneekepusi ezinemibala eziyi-85 kwiitreyi ezi-4. Inxalenye yesi-2 yethu iphefumlelwe lulo, kodwa isebenzisa imibala yethu neekepusi ezimbalwa.
  • Ubudala: kolu vavanyo lwezonyango, ukuhlela imibala kubalasele malunga neminyaka eyi-19, kuze kunciphe kancinci njengoko umntu ekhula (abantu abayi-382 ababonayo imibala ngendlela eqhelekileyo) [5].
  • Imibala edidayo: kuvavanyo lwe-intanethi lwabantu abayi-1,401 malunga nefoto "yelokhwe", i-57% bayibone iluhlaza okwesibhakabhaka namnyama, yaye i-30% bayibone imhlophe negolide [6]. Olunye uphando olukhulu lwe-intanethi lufumene ukuba uninzi lubone okwahlukileyo [7], ngoko abantu baphantse bahlukane phakathi.

Indlela olusebenza ngayo uvavanyo lokubona imibala

  1. Luhlaza okwesibhakabhaka okanye luhlaza? Umbala omnye uvela ngexesha, kwimvelaphi engwevu engathathi cala. Cofa ku-Luhlaza okanye ku-Luhlaza okwesibhakabhaka, okanye ucofe ← no-→. Khetha ngokwendlela owubona ngayo kuqala.
  2. Ukusondela kumda. Ulandelelwano lwemibala emibini luqhubeka ngaxeshanye, olunye luqala kwicala eliluhlaza nolunye kwicala eliluhlaza okwesibhakabhaka, lunemibala eyi-12 ngalunye. Impendulo ethi "luhlaza" isondeza olo landelelwano kwicala eliluhlaza okwesibhakabhaka, ethi "luhlaza okwesibhakabhaka" ilusondeze kwicala eliluhlaza, yaye amanyathelo aya esiba mancinci ngalo lonke ixesha utshintsha impendulo. Zombini zidibana kufutshane nomda wakho.
  3. Imibala ngokulandelelana. Emva koko ufumana imiqolo eyi-4 enemibala eyi-12 kumqolo ngamnye. Iziphelo zomqolo ngamnye zinemibala emiselweyo; tsala imibala, okanye ucofe emibini ukuze uyitshintshe, de umqolo utshintshe ngokugudileyo. Akukho xesha libekiweyo.

Yonke imibala eyi-52 yenxalenye yesi-2 ijikeleza isangqa semibala kube kanye, yahlulwe malunga ne-6.9° ye-hue, inokukhanya nobuninzi bombala obufanayo, ngoko kutshintsha i-hue kuphela. Umda ubalwa kwindawo ye-50% yegophe elilinganiswe kwiimpendulo zakho. Amanqaku empazamo asebenzisa umgaqo wovavanyo lwe-100-hue.

Yintoni echaphazela iziphumo zakho?

  • Isikrini sakho. Izikrini ziyahluka ngemibala, ukukhanya nendlela ezilungiswe ngayo. Imowudi yasebusuku, izihluzi zokukhanya okuluhlaza okwesibhakabhaka, i-"true tone" nesikrini esimnyama zonke zityhalela imibala kwicala lomthubi. Nomenzi wovavanyo lwezonyango lwe-100-hue uthi inguqulelo ye-intanethi ayinakunika isigqibo esiqinisekileyo, kuba iimonitha ziyahluka [8]. Thelekisa iziphumo kwisikrini esinye.
  • Igumbi. Ukukhanya okuqaqambileyo okanye okunombala okujikelezileyo kutshintsha indlela esibonakala ngayo isikrini.
  • Ulwimi lwakho. Amagama owasebenzisayo kwimibala aphembelela indawo obeka kuyo umda. Iilwimi ezibiza okuluhlaza okwesibhakabhaka okukhanyayo nokumnyama ngamagama ahlukeneyo, okanye ezibiza okuluhlaza nokuluhlaza okwesibhakabhaka ngegama elinye, zibeka imida eyahlukileyo [2][4][9].
  • Ubudala nokudinwa. Ukuhlela imibala kuba nzima njengoko umntu ekhula [5], kwaye amehlo adiniweyo akufumanisa kunzima ukuhlela imibala esondeleleneyo.
  • Indlela obona ngayo imibala. Abantu abanengxaki yokwahlula okubomvu nokuluhlaza badla ngokufumana imiqolo ethile inzima kakhulu. Ukuba ezinye iindawo zovavanyo bezibonakala zingenakwenzeka, ugqirha wamehlo okanye ingcali yamehlo inokukuvavanya kakuhle ukubona kwakho imibala.

Oko olunokukuxelela nokungenakukuxelela kona olu vavanyo

Uvavanyo lokubona imibala lubonisa indawo obeka kuyo wena umda phakathi kokuluhlaza nokuluhlaza okwesibhakabhaka, nokuba ungayilungelelanisa kakuhle kangakanani imibala efana kakhulu kwesi sikrini. Ngumdlalo osekelwe kwimisebenzi yophando. Asiluvavanyo lobumfama bemibala, asiluvavanyo lwezonyango, yaye asilulo uvavanyo lwe-Farnsworth–Munsell ngokwalo: amanqaku alo akanakuthelekiswa nemigangatho yezonyango. Asinxulumananga ne-X-Rite okanye i-Munsell.

Ukuba ucinga ukuba usenokuba yimfama ngemibala, ingcali yamehlo okanye ugqirha wamehlo unokukuvavanya esebenzisa iipleyiti ezifanelekileyo nokukhanya okulawulwayo.

Imibuzo edla ngokubuzwa

Ngaba oluhlaza okwesibhakabhaka lwam luyafana nolwakho?

Akusoloko kunjalo. Xa abantu bekhetha owona mbala wabo uluhlaza nowona uluhlaza okwesibhakabhaka, ukhetho lwabo luyahluka kakhulu; into eluhlaza okwesibhakabhaka komnye umntu inokuba luhlaza komnye [1]. Uvavanyo lukaHelibrain lokubona imibala lufumana umda wakho phakathi kokuluhlaza nokuluhlaza okwesibhakabhaka, ukuze uwuthelekise nowomhlobo kwisikrini esinye.

Ngaba umbala weturquoise uluhlaza okwesibhakabhaka okanye uluhlaza?

I-Turquoise ne-teal zisemdeni kanye phakathi kokuluhlaza nokuluhlaza okwesibhakabhaka, yiyo loo nto abantu bengavumelani ngazo. Ukuzibiza ngokuba ziluhlaza okwesibhakabhaka okanye ziluhlaza kuxhomekeke emehlweni akho, kwisikrini sakho nakulwimi lwakho: kwiilwimi eziyi-120 ezaphandwayo, ezingama-68 zisebenzisa igama elinye kuzo zombini [2]. Uvavanyo lubonisa ukuba wena utyekele kweliphi icala.

Ngaba olu luvavanyo lobumfama bemibala?

Hayi. Uvavanyo lukaHelibrain lokubona imibala aluvavanyi ubumfama bemibala kwaye alunakuxilonga nasiphi na isifo. Uvavanyo lobumfama bemibala lusebenzisa iipleyiti ezikhethekileyo nokukhanya okulawulwayo. Malunga nendoda e-1 kweziyi-12 inengxaki yokubona imibala [3][10]; ukuba ucinga ukuba unokuba nayo, bonana nengcali yamehlo okanye ugqirha wamehlo.

Kutheni iziphumo zam zitshintsha kwesinye isikrini?

Izikrini zibonisa imibala ngeendlela ezahlukeneyo, yaye useto olufana nemowudi yasebusuku, izihluzi zokukhanya okuluhlaza okwesibhakabhaka nokukhanya kwesikrini luyayitshintsha ngakumbi [8]. Umda olinganiswe kwifowuni enemowudi yasebusuku esebenzayo unokwahluka kowolinganiswe kwikhompyutha ephathekayo. Ukuze uthelekiso lube lolona lungileyo, sebenzisa isikrini noseto olufanayo ngalo lonke ixesha.

Ngaba olu luvavanyo lwe-Farnsworth–Munsell 100 hue?

Hayi. Inxalenye yesi-2 iphefumlelwe luvavanyo lwe-Farnsworth–Munsell 100 hue kwaye isebenzisa umgaqo walo wokubala amanqaku, kodwa imibala yeyethu, mincinane ngenani, yaye iboniswa kwisikrini endaweni yeekepusi eziphathekayo phantsi kokukhanya okumiselweyo. Amanqaku ethu akanakuthelekiswa nemigangatho yezonyango.

Ngaba uvavanyo lukaHelibrain lokubona imibala lusimahla ngokwenene?

Ewe. Uvavanyo nesiphumo sakho esipheleleyo simahla: akukho kubhalisa, akukho imeyile, akukho ntlawulo. UHelibrain ufumana ingeniso kwi-app yakhe, enesicwangciso sasimahla nezicwangciso ezihlawulelwayo; awuyidingi i-app ukuze wenze uvavanyo.
