The colors produced by mixing colored light. The primary
additive colors are red, green and blue. The absence of color
produces black (0%); maximum intensity produces white (100%).

per pixel it is possible to represent more than 16 million colors.

The transition from light to dark or dark to light in a smooth
uninterrupted progression. Laser and dot matrix printers do not
support continuous tones.

As contrast increases, the number of gray shades between black
and white decreases.

represent darker areas. This technology is used in devices that
only support black and white outputs.
