What’s behind? STEM tips
Pixel art is a vintage style. It comes from the past when screens, at that time, hadn’t the beautiful resolution they have now. Screens are a matrix of pixels, a single pixel is a tiny light that can be switched on and off. Each pixel is coloured because each tiny light (LED) has at least three other ones inside of it. One Red, one Green and one Blue (RGB). How you combine them determine the colour you can see.
