I know TVs and phones are made of green, red, and blue pixels, but how do they make all colors just from those three colors?

Answer 1

They roughly correspond to the structures in our eyes. We have structures in our eyes called rods and cones. Rods are more about peripheral vision, and low/bright light (among other things). We have 3 cone structures. One responds to red wavelengths, one responds to green, and one responds to blue. All the colors we can see are a combination of how these cones talk to our brain.
