CRT screens display images by moving beams of electrons very quickly across the screen. Once the beam of the monitor has reached the edge of the screen, it is switched off, and the deflection circuit voltages (or currents) are returned to the values they had for the other edge of the screen; this would have the effect of retracing the screen in ...

Third, color 0 (the "background" color) can be set to any of the 16 colors. The specific BIOS graphics mode influences which palettes are available.
