Despite all the colours depicted on our screens, there are only three coloured pixels.
Yes, it’s true that despite the wide array of colors we perceive on screens, such as those on computer monitors, televisions, and smartphones, the basic elements responsible for producing those colors are typically limited to just three primary colored pixels. This concept is commonly referred to as the “RGB color model.”
In the RGB color model, colors are created by mixing different intensities of red, green, and blue light. These three primary colors are combined in various proportions to produce a vast range of colors. By adjusting the intensity of each of these three primary colors, screens can create different hues and shades that our eyes perceive as a wide spectrum of colors.
So, while we might see a rich tapestry of colors on our screens, they are indeed composed of just three primary colored pixels: red, green, and blue.

I’m buggered if I know how you get yellow out of red, blue and green. I’m guessing subtracting the blue from the green.
But since I have mild red-green blindness, WTF would I know ? I can differentiate red and green in their pure forms but dirty browns and greens look the same. Dark blue and purple are interchangeable in my world and pinks and greys are too.

Hi Mike, I did some research on this:
Yellow is created by combining red and green light in equal intensities, without any blue light. In the RGB color model, which is commonly used in electronic displays such as computer monitors and television screens, different colors are produced by varying the intensities of red, green, and blue light.
When red and green light are mixed together at full intensity, they produce yellow light. This is because the human eye perceives the combination of red and green light as yellow. Therefore, in RGB color space, to create the color yellow, the red and green components are both set to their maximum intensity, while the blue component is set to zero.
So, even though we perceive a wide range of colors on our screens, including yellow, it all boils down to the manipulation of just three colored pixels—red, green, and blue—in various combinations and intensities.
Who’d of thunk it!
