RGB idapangidwa kuchokera pamawu a kuwuka. Mu mawu a Sing'anga, njira yake yosakanikirana imakhala ngati magetsi ofiira, obiriwira, komanso abuluu. When their lights overlap each other, the colors are mixed, but the brightness is equal to The sum of the brightness of the two, the more mixed the higher the brightness, that is, additive mixing.

Iliyonse mwa njira zitatuzi, zofiira, zobiriwira, ndi buluu, zimagawidwa milingo 256 yowala. Pa 0, "kuunika" ndiko kufooka kwambiri - kumazimitsidwa, ndipo pa 255, kuunika "ndiko chowala kwambiri. When the three-color grayscale values are the same, gray tones with different grayscale values are generated, that is, when the three-color grayscale is all 0, it is the darkest black tone; Pamene mitundu itatu yazithunzi ili 255, ndiye mawu oyera oyera.

RGB colors are called additive colors because you create white by adding R, G, and B together (that is, all the light is reflected back to the eye). Mitundu yowonjezera imagwiritsidwa ntchito poyatsa, pa TV ndi oyang'anira makompyuta. Mwachitsanzo, zowonetsera zimapanga utoto potulutsa kuwala kuchokera kufiyira, zobiriwira, ndi blussors. The vast majority of the visible spectrum can be represented as a mixture of red, green, and blue (RGB) light in varying proportions and intensities. Mitundu iyi ikadzaza, Cyan, Magenta, ndipo wachikasu amapangidwa.

Magetsi a RGB amapangidwa ndi mitundu itatu yoyambirira yophatikizidwa kuti apange fano. Kuphatikiza apo, palinso madambo abuluu okhala ndi Phossors achikasu, ndi ma altraviolet amapita ndi phosgors. Nthawi zambiri onse ali ndi mfundo zawo zofunika.
