I-HEX ne-RGB: izindlela ezimbili zokubhala umbala ofanayo
Wonke umbala owubona esikrinini uxutshwe ngezibani ezintathu: obomvu, oluhlaza kanye noluhlaza okwesibhakabhaka. Vula konke kokuthathu kuphakame khona ubuye uthole umhlophe; cima konke uthole umnyama. I-HEX ne-RGB ziyizindlela ezimbili nje zokuchaza ukuthi umgudu ngamunye kulokho kuthathu kufanele ukhanye kangakanani. Zikhomba umbala ofanayo ngokuqondile, ngakho umguquli omuhle uhumusha nje phakathi kwezindlela ezimbili zokubhala ngaphandle kokuguqula umbala wangempela nhlobo. Yilokho leli thuluzi elikwenzayo, ngokuphelele ngaphakathi kwesiphequluli sakho, likhombisa isibonelo esiphilayo somqondo ukuze uqinisekise umphumela ngamehlo akho.
Indlela yokufunda ikhodi ye-hex
Umbala we-hex ubukeka njenge-#1E90FF. Uphawu lwe-hash likhomba nje ukuqala; izinhlamvu eziyisithupha ezilandelayo amabili amabili amathathu, abhalwe ngephethini elithi #RRGGBB. Amabili okuqala abomvu, amabili esibili oluhlaza, amabili esithathu oluhlaza okwesibhakabhaka. Amabili ngamanye inombolo ebhalwe ku-hexadecimal, okusho isisekelo se-16, lapho amadijithi ehamba kusuka ku-0-9 bese ku-A, B, C, D, E, F emele u-10 kuya ku-15. Amabili anganikeza amanani asuka ku-00 (umgudu ucishiwe ngokuphelele) kuya ku-FF (uvulwe ngokuphelele). Ngedesimali ejwayelekile leyo bakhelo isuka ku-0 kuya ku-255, izinga elifanayo i-RGB elisebenzisayo. Ngamazinga angu-256 angenzeka umgudu ngamunye, ifomu elinamadijithi ayisithupha lingachaza imibala ehlukene engu-16,777,216.
Ukuguqula ngazo zombili izindlela, nesibonelo esisebenzayo
Ukusuka ku-HEX uye ku-RGB, hlukanisa ikhodi ibe amabili ayo amathathu bese uguqula amabili ngamanye asuka esisekelweni se-16 aye kudesimali ejwayelekile. Thatha i-#1E90FF. Amabili obomvu 1E: leyo yi-1 iphindwe ka-16, kwengeziwe ku-14 (E), okulingana no-30. Amabili aluhlaza 90 ayi-9 ephindwe ka-16, kwengeziwe ku-0, okulingana no-144. Amabili aluhlaza okwesibhakabhaka FF ayi-15 ephindwe ka-16, kwengeziwe ku-15, okulingana no-255. Ngakho i-#1E90FF iphenduka i-rgb(30, 144, 255) — umbala oluhlaza okwesibhakabhaka odumile owaziwa ngokuthi dodger blue.
Ukuya ngakolunye uhlangothi kuyinqubo efanayo kodwa kuphenduphenduka. Thatha inombolo ngayinye ye-RGB futhi uyibhale ibe amadijithi amabili we-hex. Obomvu oqotho, i-rgb(255, 0, 0), unikeza i-FF, 00 ne-00, ehlanganiswa ibe i-#FF0000. Into eyodwa okumele uyikhumbule: uma inani lingaphansi kuka-16, usadinga amadijithi omabili, ngakho u-5 ubhalwa njenge-05 hhayi nje u-5. Umguquli uyakuphatha lokho kugcwaliswa ngokwakho, kodwa kuwisa abantu uma bekwenza ngezandla.
Lapho ifomethi ngayinye isetshenziswa khona
I-HEX ulimi lwansuku zonke lwewebhu. I-CSS, i-HTML kanye nekhodi eyiningi oyibhalayo zithatha amakhodi we-hex ngoba afinyeziwe futhi kulula ukuwakopisha. I-RGB ivame ukuvela ngaphakathi kwamathuluzi okuklama nezithombe — i-Figma, i-Photoshop, i-Sketch kanye ne-Illustrator ngokuvamile ikhombisa izikhwexisi noma amasimu esikaleni sika-0-255, futhi izinhlelo zokuqoshwa kwesikrini noma amavidiyo nazo zivame ukudinga i-RGB. Ngakho uvame ukuthatha ikhodi ye-hex ohlelweni lwesitayela bese udinga ifomu layo le-RGB ukuze uyithayibhe ephaneli lokuklama, noma ngokuphambene. Lolo hambo oluye nemuva yisizathu sonke sokuthi umguquli usiza ngani. Uma udinga ukwakha uhlu olugcwele lwemibala efanayo esikhundleni sokuguqula owodwa, umkhiqizi wethu we-uhlu lwemibala uyindawo engcono yokuqala, futhi uzothola amanye amathuluzi afana nalawa ngaphansi kwe-amathuluzi omthuthukisi.
I-Alpha, ukubonakala kanye ne-HSL
Zombili izindlela zibhalwa zinefomu elinwetshiwe elengeza ukubonakala. I-RGB iphenduka i-rgba(30, 144, 255, 0.5), lapho inani lesine kuyi-alpha — u-0 ubonakala ngokuphelele bese u-1 uqinile ngokuphelele. I-HEX yengeza amabili esine ngenjongo efanayo, inikeza ikhodi enamadijithi ayisishiyagalombili i-#RRGGBBAA; u-80, isibonelo, cishe amaphesenti angu-50 okungabonakali. Abanye abaguquli baphinde banikeze i-HSL (hue, saturation, lightness), echaza umbala ngendlela umuntu angase acabange ngayo — khetha umgqumo esondweni, bese udayela ukugqama nokukhanya kwawo. I-HSL wumqondo owahlukile esikhundleni sohlu lwemibala olwehlukile, ngakho ingase ibe lula uma ufuna ukuguquza umbala ukhanye kancane noma ube mnyama kancane ngaphandle kokubambisana namanani amathathu ahlukene.
Imibuzo evame ukubuzwa
Ingabe uphawu lwe-hash luyingxenye yekhodi ye-hex?
I-hash iwuphawu olutshela i-CSS namathuluzi okuklama ukuthi unikeza umbala we-hex. Umbala ngokwawo yizinhlamvu eziyisithupha ezilandela lona. Amathuluzi amaningi asamukela ikhodi kokubili nge-hash noma ngaphandle kwayo bese ekwengeza kabusha.
Yini umehluko phakathi kwekhodi enamadijithi amathathu neyamayisithupha ye-hex?
Ikhodi enamadijithi amathathu isifinyezo lapho idijithi ngayinye iphindaphindwa, ngakho i-#1AF isho i-#11AAFF. Ifinyelela kuphela imibala engu-4,096, kanti ifomu eligcwele lamadijithi ayisithupha lifinyelela ngaphezu kuka-16 million.
Kungani ikhodi yami ye-hex inezinhlamvu eziyisishiyagalombili?
Ikhodi ye-hex enamadijithi ayisishiyagalombili yengeza amabili esine we-alpha, noma ukubonakala. Izinhlamvu eziyisithupha zokuqala zisadinga obomvu, oluhlaza kanye noluhlaza okwesibhakabhaka, kanti amabili okugcina asetha ukungabonakali kusuka ku-00 (okungabonakali) kuya ku-FF (okuqinile).
Ingabe amakhodi we-hex ahlukanisa unobumba abakhulu nabancane?
Cha. I-#1e90ff ne-#1E90FF zichaza umbala ofanayo ngokuqondile. Unobumba wesizinda se-hexadecimal usebenza ngokufanayo kokubili unobumba abakhulu noma abancane, ngakho sebenzisa noma yikuphi ithimba lakho elikuncamelayo.
Ingabe i-HEX ne-RGB ziyake zibukeke zihlukile esikrinini?
Cha. Uma zichaza amanani omgudu afanayo zingumbala ofanayo ngokuphelele. Noma yimuphi umehluko obonakalayo uvela ephuthweni lokubhala noma kwelinye ikhodi elifaka ukubonakala elinye elingakufaki.
Ingabe ikhodi ye-hex ejwayelekile ingakhombisa imibala emingaki?
Ikhodi ye-hex enamadijithi ayisithupha inikeza amazinga angu-256 kumgudu ngamunye kokuthathu, okuphindaphindeka kube imibala engaba yizigidi ezingu-16,777,216 engenzeka.
