Televisions, and nearly all other computer screens use red, blue and green because they are the three colours light is made of. This is different to what colour you get by mixing paint.
Colours are created by which different parts of the light spectrum an object reflects. Mixing paint which reflects blue with paint which reflects yellow will create a combination which reflects green.
In the light spectrum:
Blue + Green = Aqua (Light blue)
Green + Red = Yellow
Red + Blue = Magenta (Pink)
The primary colours in art are red, yellow and blue. The pixels on a colour TV uses red, yellow and green.
RGB, or red, green, and blue are the colors that make up the pixels on a tv or computer screen. some newer tv's also have black or yellow pixels in addition.
A very close-up of a TV screen shows pixels of red, yellow and green.
Red green and blue
The 'pixels' on a TV screen are red, blue, and green.
The third primary colour of light besides red and blue is green. This is why colour televisions contain red, blue and green pixels.
Red Black and White or maybe instead of black it might be gray
Red , yellow and green
Red, Green and Blue.
Green is a mixture of yellow and blue, if you mix all the primary colours together you will get brown. This would be the same if used green instead of just yellow.
Yellow is a primary color in pigments. This means you must start with yellow paint. In projected lights, such as theatre lights or tv/computer monitors, mix red and green light for yellow light.
Yellow is a primary color. The only situation in which you would mix colors to create yellow would be in an additive model such as RGB, as is used in television displays, where yellow is created from adding thewavelengths ofred and green.
