Pixels on a computer screen

Each pixel on a screen is made up of smaller units called subpixels, and these subpixels can display different colors by combining red, green, and blue light. These are known as the primary colors of light in the RGB (Red, Green, Blue) color model.

How the colors are controlled

The colors on the screen are controlled by combinations of binary numbers (1s and 0s). Each subpixel (red, green, or blue) can be adjusted in intensity by a sequence of these 1s and 0s.

d) Black

• This is as well incorrect, black occurs when no light is emitted.
