Simulating TV/Monitor Screens with Python Turtle

Today’s computer monitors and TVs consists of a lot of tiny Red, Green, and Blue pixels. By adjusting the level of brightness of these three pixels, we can make all other colors we see on screen. In this project, we are going to test this ourselves.

Draw a matrix of small dots in red, green, and blue with the pattern shown below:

Red, Green, Blue dots that make up the computer screen

Now make the dot much smaller and fill up the same space. You should see something like below. The vibrant colors of previous picture disappears and we see a gray color.

Let’s turn off the blue dots by replacing them with black dots. Only red and green dots remain. Does it display some yellow color as shown in below?
