# 48 03 15 Red Green Blue Digital Color RGB to HEX

Color Pixels Each pixel composed red, green and blue phosphers with black mask. Each channel of the RGB has brightness levels between 0 to 255. Total number of possible colors is 256*256*256 = 16,777,216 The human eye blends RGB pixels into range of other colors depending on the light.

Color Saturation Color Saturation is how bright or dull the color is Color Saturation on the computer is controlled by the intensity of the electrons firing in the RGB filters. High intensity means more light coming through the color phosphers which makes the screen color brighter Lower intensity means less light coming through the color phosphers which makes the screen color duller.

The Way it Works All phosphors without electrons firing gives black color All phosphors with full electron intensity gives white All phosphors equal amount electrons at lower intensity gives gray Pixel

The Way it Works All red phosphors gives red color at high intensity All green phosphors at high intensity gives green All blue phosphors at high intensity gives blue Pixel

The Way it Works Pixel Green & red at high intensity display yellow Green & blue at high intensity display cyan Blue & red at high intensity display magenta Pixel

Different brightness level RGB combos create different pixel colors The Way it Works Different brightness level RGB combos create different pixel colors Green at lower intensity & red at higher intensity can create orange Green at lower intensity & red at higher & blue at higher intensity can create pink Green at higher intensity, blue at higher intensity & red at lower intensity can create light blue Pixel
