Summary

On a color monitor each group of phosphor dots is made up of one green, one blue and one red dot (RGB). By varying the brightness of each of these primary colours, color monitors can create an unlimited number of colors.

The reconstruction of colors is based on additive color. Sliders adjust the intensity levels for each color (Red, Green, Blue).

Red, green and blue are the three primary colors. As indicated in the simulation additive color, mixing can generate four colors: Cyan (green + blue), magenta (red + blue), yellow (red + green) and white (the sum of three). Since the late nineteenth century, we have known that it is possible to generate all known colors playing on the intensities of the primary colors. This allows to generate all the colors of the rainbow as shown the simulation RGB.

The screens display color images with a principle called trichromatic colorimetry. This is the way our eye perceives color.
Note: The letters RGB are often used to identify the three colors.…
