Kulesi sihloko ngizokutshela okuncane ngemfundiso mbala esetshenziswe ezikrinini. Ngale ndlela uzokwazi kangcono ukuthi ukukhetha kombala kusebenza kanjani ezinhlelweni ezifana ne-Photoshop.
Sinemibala ehlukahlukene etholakalayo, futhi ingxenye enkulu, sichaza umbala ngendlela eyenza kube nzima ukubona ubudlelwano phakathi kwemibala ehlukene. Amagama afana nokubomvu, okuluhlaza okotshani, oluhlaza okwesibhakabhaka, ophuzi, onsomi, nonsundu ngamagama abanzi ezingxoxweni ngemibala kepha anikeza ukuqonda okuncane ngesakhiwo salo mbala. Kusukela lapho singakhuluma khona, umbala ucutshungulwa yingxenye yolimi lobuchopho bethu futhi nencazelo yawo iboshelwe kumagama esiwanikeza imibala.
Ngakolunye uhlangothi, ubukhulu bucutshungulwa ngokuhlukile ubuchopho bethu. Silinganisa ubukhulu besimo esilingana nokwenyuka okungaguquguquki futhi kwaziwa kahle njengamasentimitha noma amasentimitha. Le mibono yokulinganisa iza ngokwemvelo kithi futhi, ngenkathi umbala ungalinganiswa futhi uchazwe ngokufanayo, imvamisa kunzima kakhulu ukuba siqonde futhi sisebenzise umbala njengesilinganiso sezingxenye zawo.
Kwaze kwaba yilapho u-Isaac Newton enza uchungechunge lwama-prism ngo-1600, ngaphambi kokuthi siqale ukuqonda ukuthi ukukhanya kwakhiwa ngemibala ehlukene engalinganiswa ngokuzimela komunye nomunye. Kusukela ngaleso sikhathi, amasondo ombala amukelwa ngabadwebi ukuze baqonde kangcono futhi bahlanganise imibala.
Ngenkathi iningi labaculi lisebenzisa umbala obomvu, ophuzi noluhlaza okwesibhakabhaka njengemibala eyinhloko, futhi amakilasi amaningi emfundisweni yemibala abhekisela kule njengemibala eyinhloko, isayensi iguqukile kusukela ezinsukwini zika-Isaac Newton. Amehlo aqukethe izamukeli ezimbalwa zokukhanya. Abamukeli babizwa nge- «imisele»Thola izithunzi namalambu, kanye ne-«Izigaxa»Thola imibala emithathu eyinhloko: obomvu, oluhlaza okotshani nokuhlaza okwesibhakabhaka.
Le mibala emithathu eyinhloko ngokuqinisekile izojwayeleka kulabo bethu abasebenza nezinhlelo ezinjenge-Photoshop, ngoba iyindlela esinquma ngayo imodi yombala (RGB). Abaqaphi banezingxenye ezibomvu, eziluhlaza nokuhlaza okwesibhakabhaka kwiphikseli ngayinye. Umbala ngamunye unokuhluka okungama-256 ekukhanyeni lokho kubangela ingqikithi yamathuba wemibala ehlukene ayi-16.777.216. Singachaza umbala kuwebhu noma ku-Photoshop ngomsebenzi wombala we-RGB rgb (255,115,0) noma amanani we-hexadecimal # FF7300, womabili achaza umbala ofanayo ngendlela ehluke kancane.
Umbala ohlobene
Ukuqala ukucabanga ngombala nobudlelwano bawo singaqala ngomsebenzi wombala I-CSS hsl (). Lo msebenzi wephula umbala ku-hue, saturation nokukhanya. I-Hue ivezwa njengeziqu ngaphandle kophawu lwedigri (ngaphandle kwama-360) ngenkathi ukugcwala nokukhanya kukhonjiswa njengamaphesenti ngaphandle kophawu lwamaphesenti (kwayi-100).
Ngakho-ke, i- "hue" ivezwa njengevelu engu-360. Leli nani linikezwa isondo lemibala. Cabanga, cabanga noma ubone ngeso lengqondo isondo lemibala. Uma une-red (0) futhi ufuna ukwenza okuphuzi, ungavele uhambise umbala ube ngu-60. Emcabangweni wombala kunomqondo wemibala ehambisanayo, okuyimibala emibili ezinhlangothini eziphambene zesondo lombala. Ukuthola umphelelisi obomvu kuzodingeka uthole inani elingu-180 ° elizungeze isondo elibomvu. Kulokhu u-0 ngokubomvu uhlanganise no-180 futhi umbala ovelayo uluhlaza.
Ukugcwala nokugqama kulula ukukuqonda. Umbala ogcwele ngokugcwele (100) awunampunga nhlobongenkathi ukugcwaliswa okungu-0 esivele sikhulume ngakho, isibonelo, isithombe esimpunga. Ngokucwebezela, u-0 umnyama kuthi u-100 umhlophe. Ukulungisa la magugu phezulu nangaphansi kuzokwenza umbala okhethiwe ube lula noma ube mnyama. Ngoba umbono wethu wombala uvame ukuboshelwa kumbala wombala, kulula kakhulu ukucabanga ngokugcwala nokukhanya ngokwesilinganiso.
