Ngoko enye bit buqonda iperi lwamaxabiso, amasuntswana ezimbini zenzelwe ujiko amaxabiso ezine, amasuntswana ezintathu - anesibhozo. Ukongeza utsotsi, ungenza kabini inani lwamaxabiso ekwi khowudi. Ngoko ke, lo amasuntswana 8 encoder ulandelelwano 256 (values) kwi khowudi yokubini. Into ephawulekayo kukuba ngolandelelwano nganye zigcinwe, ubuchule bokukhupha umlinganiswa isicatshulwa. Isixhobo esisesinye khowudi ziikhowudi ezisibhozo ke ikhowudi kwi-16 no-32-bit, banalo na amandla kunye nokulungiswa 65.536, ngokulandelelana, 4294967296 abalinganiswa yombhalo.

Ukusebenzisa le HTTP protocol, ikhutshwa phandle inkqubo kokuthumela ibhrawuza web kumncedisi imiyalezo, ezafumana, umncedisi uthatha iphepha efunekayo yaye liguqulelwe ngayo (olushicilelayo) ngendlela efunekayo.

Ukuze ufumane umbala olifunayo kwi esweni kufuneka ezixutywe olinganise wacela imibala yokuqala - obomvu (Red), eluhlaza (Green), kunye oluhlaza (Blue). Ngoko ke, lo ungeno kwi RGB ikhowudi umbala esulungekileyo ebomvu Kubonakala ngathi rgb (255,0,0). iseti yamanani kwizibiyeli umbala oluhlaza kuya kwenziwa kukhethwe 0,255,0, kuba blue - 0,0,255. Classically umbala omthubi coded indibanisela 255,255,0 nemisonto ekwafanekisa ikhowudi 255,0,255. Xa chislosochetanie black kukhangeleka ngathi 0,0,0, ubumhlophe 255.255.255 kunye 192.192.192 hina.

Umelo ngentla umbala unikwa ecacileyo, html ikhowudi kukusebenzisa ngobhalo njengokom (HEX), oqala #. Xa ubhala ikhowudi HEX umbala omnyama uchazwa # 000000, White - #FFFFFF, ibe ngwevu - # C0C0C0. Usebenzisa ikhowudi kwi imibala yokuqala ebomvu, eluhlaza nangemisonto tlakukeke # FF0000, # 00FF00, # 0000FF, ngokulandelelana.
