We've blinked an LED and controlled eight in sequence. Now it's time to control color. Using an RGB LED (actual 3 LEDs in a single housing) we can generate any color our heart desires. 

We do this through color mixing, what’s required is delving back to your elementary art days of playing with colored cellophane to produce different colors (if you can’t remember that far back don’t worry here’s a color wheel to help you out).
