This uses different colors(red, green, and blue, the 3 colors used to make pixels) to make satisfying displays. Make sure to turn on Turbo Mode(hold shift and press flag) DO NOT FULL-SCREEN! IT WILL NOT WORK FOR SOME REASON!
The three colors used to make pixels work are red, green, and blue. A monitor uses these lights at different values to make (almost) all colors appear on the screen. These lights are very small and are invisible to the naked eye on most screens nowadays. If you look closely at old tvs/monitors you can see the lights. Using this information, I tried to make a screen, but it didn't work very well, and it turned into this.
