Computers use RGB because their screens emit light. The primary colors of light are RGB, not RYB. There's no yellow in this square: It just looks yellow..
Moreover, why is it RGB and not RBY?
It is (virtually) impossible to mix Red Green Blue paint into Yellow paint, or mixing Red Yellow Blue light into Green light. The basic colours are RGB not RYB. Cyan, Magenta and Yellow are "subtractive colors". If we print cyan, magenta and yellow inks on white paper, they absorb the light shining on the page.
why do we use RGB instead of primary colors? For an additive system, light is created directly. This means that the primary colors of the most effective additive color system are simply red, green, and blue (RGB). This is why most computer screens, from iPods to televisions, contain a grid of little red-, green-, and blue-emitting light sources.
Keeping this in view, what is the difference between RGB and RYB?
It is hard to believe, but these are same hues but at different values. Second difference: The RYB subtracts red and blue to make purple. CYM/RGB subtracts from magenta to make both red and blue. Ostwald, who defined color on a scientific basis, defined opposite colors on the colorwheel as the afterimage of the color.
Why do TVS use RGB?
The name of the model comes from the initials of the three additive primary colors, red, green, and blue. The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography.

Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Closer to the horizon, the sky fades to a lighter blue or white.Why do computers use RGB?
This is because they are reflecting light. Traditionally, additive colors (RGB) are used because the canon for computer graphics was the computer monitor, and since it's emitting light, it makes sense to use the same structure for the graphic card (the colors are shown without conversions).Is green a primary Colour?
