Lab description and primary aims of the lab: 

You will see that there is a difference between reality and theory.

  • Use this difference to investigate and find out what is the reason that light around us show colors that we perceive differently in reality.
  • Use the three sliders (red, green and blue) to select your color combination.
  • Then send the new values to the RGB led and compare the real result with the virtual color square below the sliders.
  • Each slider controls one of the three primary colors. Move each of them to get the desired color combination.
  • Once obtained it comparing the color of the bulb with digital color that it is displayed in the laboratory.
