I-RGB ikunikeza iziteshi ezintathu zedesimali phakathi kuka-0 no-255. Ukuguqula ku-HEX kuguqula isiteshi ngasinye sibe yinombolo ye-hexadecimal enedijithi ezimbili, ukuze yonke imibala ifaneleke kuthekhenika eyodwa ecashile eqondwa yibhrawuza ngalinye, ithuluzi lokuklama nomhlahlandlela wesitayela.
Indlela okuhunyushwa ngayo RGB kuya ku-HEX
- Thatha i-red channel uyihlanganise ngo-16: isabelo siwudijithi wokuqala, okulodwa okuwukusele kuyidijithi yesibili.
- Bhala izinombolo 10 kuya ku-15 njengamaleta A kuya ku-F — 255 iba FF.
- Phinda ngenombala oluhlaza (green) nowoluhlaza-okwesibhakabhaka (blue), ugcwalise amadijithi ayi-single ngenombolo ngaphambili: 5 iba 05.
- Hlanganisa ama-pairs amathathu bese ufaka # phambi kwawo.
Isibonelo esisebenzayo
Kuyiqiniso, uma nje ama-channel enguwo wonke (whole numbers) kusuka ku-0 kuya ku-255. Amaxabiso anezigaba ezifana ne-rgb(79.5, 70, 229) ziyi-rounded ku-integer eseduze kuqala, ngoba i-HEX ayikwazi ukugcina okuphakathi.
RGB no-HEX kuchazwe
Iyini RGB?
I-RGB ichaza umbala njengesiteshi sesithathu sokukhanya — red, green kanye ne-blue — ngakunye kusuka ku-0 kuya ku-255. Ikhombisa ukuthi izikrini zisebenza ngempela: zonke ezintathu ku-255 zenza umhlophe, zonke ku-0 zenza mnyama. I-RGB ifanele uma kudingeka ukubala ngombala, kanti i-rgba() yengeza ukuphelelwa ukucacisa.
- Isakhiwo:
- rgb(R, G, B)
- Ibanga:
- 0–255 per channel
- Ilungele:
- ikhodi, canvas, ukuphelelwa ukucacisa nge-rgba()
Iyini HEX?
Ikhodi ye-HEX iyi-hexadecimal yezinombolo eziyisithupha egcina iziteshi ezibomvu, eziluhlaza kanye neziluhlaza okwesibhakabhaka zombala ngemuva kwe-#. Iphara ngalinye lamadijithi limela isiteshi esisodwa, kusuka ku-00 (akukho) kuya ku-FF (kugcwele), okunikeza imibala eyizigidi ezingama-16.7 njengase-RGB ngokufaka okubhaliwe okufushane. I-HEX iyinketho ezicini ze-CSS, amathuluzi okwakha nomhlahlandlela webhrendi.
- Isakhiwo:
- #RRGGBB
- Ibanga:
- 00–FF per channel
- Ilungele:
- CSS, ukudluliswa kokuklama, imihlahlandlela ye-brand
Ithebula lokubhekisela le-RGB kuya ku-HEX
Imibala ye-CSS evame ukusetshenziswa, iguqulwe ukusuka ku-RGB iye ku-HEX.
