Kule nqaku ndiza kukuxelela kancinci malunga nembono yethiyori esetyenziswe kwizikrini. Ngele ndlela Uyakwazi ukwazi ngcono ukuba ukhetho lombala lusebenza njani kwiinkqubo ezinjenge-Photoshop.
Sinemibala eyahlukeneyo eyahlukeneyo, kwaye ubukhulu becala, sichaza umbala ngendlela eyenza kube nzima ukubona ubudlelwane phakathi kwemibala eyahlukeneyo. Amagama anjengobomvu, luhlaza, luhlaza okwesibhakabhaka, tyheli, mfusa, kunye nomdaka ngamagama abanzi encoko ngemibala kodwa anike ukuqonda okuncinci kulwakhiwo laloo mbala. Ukususela kumzuzu esinokuthetha ngawo, umbala uqhutywa yinxalenye yolwimi lobuchopho kwaye intsingiselo yawo ibotshelelwe kumagama esiwanika imibala.
Ubukhulu, ngakolunye uhlangothi, buqhutyelwa ngokwahlukileyo ngeengqondo zethu. Silinganisa ubungakanani besimo esilingana nokunyuka rhoqo kunye nokwaziwa njengee-intshi okanye iisentimitha. Ezi zimvo zokulinganisa ziza ngokwendalo kuthi kwaye, ngelixa umbala unokulinganiswa kwaye uchazwe ngokufanayo, kuhlala kunzima kakhulu kuthi ukuba siqonde kwaye sisebenzise umbala njengenyathelo lamalungu alo.
Kuze u-Isaac Newton enze uthotho lwezilingo nge-prism ngo-1600 apho saqala ukuqonda ukuba ukukhanya kwenziwe ngemibala eyahlukeneyo enokulinganiswa ngokuzimela. Ukususela kuloo mzuzu, amavili ombala amkelwe ngamagcisa ukuze aqonde ngcono kwaye axube imibala.
Ngelixa uninzi lwamagcisa lusebenzisa obomvu, tyheli, naluhlaza okwesibhakabhaka njengemibala ephambili, kwaye uninzi lweeklasi kwithiyori yemibala zibhekisa kwezi njengemibala ephambili, isayensi iguqukile ukusukela ngemihla ka-Isaac Newton. Amehlo aqulathe izinto zokukhanya ezahlukeneyo. Abamkeli babizwa «Iinqanawa»Fumana izithunzi kunye nezibane, kunye«iikhoni»Bafumanisa imibala emithathu ephambili: obomvu, oluhlaza kunye nohlaza okwesibhakabhaka.
Le mibala mithathu iphambili iqhelekile kuthi abo basebenza neenkqubo ezinje ngeFotohop, kuba yindlela esibona ngayo imo yombala (RGB). Iimonitha zinamacala abomvu, aluhlaza kunye noluhlaza okwesibhakabhaka kwipikseli nganye. Umbala ngamnye unokwahluka okungama-256 ekukhanyeni ezenza ukuba iyonke yi-16.777.216 eyahlukileyo yemibala eyahlukeneyo. Singawuchaza umbala kwiwebhu okanye kwi-Photoshop ngomsebenzi wombala we-RGB rgb (255,115,0) okanye amaxabiso hexadecimal # FF7300, omabini achaza umbala ofanayo ngendlela eyahlukileyo.
Umbala ohambelanayo
Ukuqala ukucinga ngombala kunye nobudlelwane bayo sinokuqala ngomsebenzi wombala CSS hsl (). Lo msebenzi wophula umbala kwi-hue, ukugcwala kunye nokuqaqamba. I-Hue ibonakaliswe njengedigri ngaphandle kwesimboli (ngaphandle kwe-360) ngelixa ukugcwala kunye nokuqaqamba kubonisiwe njengepesenti ngaphandle kwesimboli yepesenti (ngaphandle kwe-100).
Ke ngoko, "hue" ibonakaliswe njengexabiso elingama-360. Eli xabiso labelwa ivili lemibala. Khawufane ucinge, cinga okanye ube nomfanekiso-ngqondweni wevili lombala. Ukuba ubomvu (0) kwaye ufuna ukwenza tyheli, unokuhambisa nje umbala ube ngama-60. Kwithiyori yemibala kukho umxholo wemibala ehambelana, eyimibala emibini kumacala ajongene nevili lemibala. Ukufumana umphelelisi obomvu kuya kufuneka ufumane kuphela ixabiso elili-180 ° ejikeleze ivili kubomvu. Kule meko u-0 ubomvu ngokudibanisa ne-180 kwaye umbala osiphumo uluhlaza.
Ukugcwala kunye nokuqaqamba kulula ukuyiqonda kancinci. Umbala ogcwele ngokupheleleyo (100) awunayo ngwevu kwaphelangexesha Ukugcwaliswa kwe-0 esele sithethile ngayo, umzekelo, umfanekiso omnyama. Nge-gloss, 0 umnyama kwaye i-100 imhlophe. Ukulungelelanisa la maxabiso phezulu nasezantsi kuya kwenza umbala okhethiweyo ube lula okanye ube mnyama. Kuba umbono wethu wombala uhlala ubotshelelwe kumbala wombala, kulula kakhulu ukucinga ngokugcwala kunye nokukhanya ngokwenqanaba.
