How does a multi color LED work?
Multi Color LED’s actually contain two pn junctions that are connected in reverse-parallel i.e. they are in parallel with anode of one being connected to the cathode of the other. If a multicolour LED is switched fast enough between two polarities, the LED will produce a third colour.
How do LEDs produce different colors?
LEDs produce different colors by using various materials which produce photons at different wavelengths. Those individual wavelengths appear as light of different colors. High-brightness red and amber LEDs use the aluminum indium gallium phosphide (AlInGaP) material system.
How many colors can LEDs make?
There is no way that LEDs can create 16.7 million different colors. While LED’s may be able to make that many colors, in reality, those millions of colors are not discernable to the human eye. So, realistically LED’s were only able to produce 10 – 15 colors.

How are colors produced on a computer screen?
Colors on A Computer Screen. The phosphors emit light when struck by the electron beams produced by the electron guns at the rear of the tube. The three separate phosphors produce red, green, and blue light, respectively. A sketch of a pixel showing the red, green and blue color produced by the three phosphors.
What are the combinations of three primary colors?
Mixtures of Three Colors Mixtures of two or three primary colors with different intensities give the other colors. The combinations for orange (red with a little green), neon pink (red with a little green and a little blue), and turquoise (blue and green with a little red) are shown below.
