Working of RGB LED

Using RGB LED, you can of course produce red. Green and blue light and by adjusting the intensity of led you can produce others colors too. Also, It is possible to produce precise dynamic color control as well. On each color scale you can select 256 levels or shades of that color. If you have three primary colors and each one can have 256 different shades, then by mixing them together you can mathematically generate 16.7 million different colors.  255 x 255 x 255 = 16,581,375.

For example: If you want to produce Red light then you’d set the Red LED at higher intensity and green & blue led at lower intensity.

If you want to make any color other than primary colors then mix all the three colors in different intensities and to adjust the intensity you can use PWM signals.
