Our video explains how screen devices produce the colors we see. We introduce a few information of the transition from black and white TVs to colors ones and ask the audience how many colors screen devices are able to reproduce. With three LEDs we demonstrate the RGB additive method and recording cell phones screens under a microscope we show real devices working. Then, we say that a pixel is able to produce around 17 million colors.
