The Tiny World of Pixels

A Pixel is the smallest element in a digital screen, which can show colors. Your screen is made up of millions of Pixels, that change colors depending on what to show on the screen. Each pixel is rectangular and can show 3 colors. Red, Green, and Blue, RGB for short. You may have heard the word RGB before. They show only these 3 colors because any color can be created with these 3 colors.

Simply put, a Pixel has 3 subpixels, each showing a color from RGB. They can change their percentage of brightness, allowing us to show a variety of colors on the screen. You want to see a Yellow flower on screen, The red and green lights brightly show yellow. If you want to see white on the screen, all 3 light up, for black, all three are off. That's one of the reasons, using dark mode saves battery.

So that is why these devices can show us a variety of colors
