   The Full color 5mm LED from RadioShack (276-0028) has 4 leads:
   (from the flat side of the LED body) 
   pin 1 Red (-)
   pin 2 Positive Voltage
   pin 3 Blue (-)
   pin 4 Green (-)
  
  To trigger the desired color you set the pin to ground.  
 so- if you want red, you would have voltage on pin 2 and pin 1 to ground. 
  
   Here is the way this works a higher PWN number on analogWrite the LED will
see a higher voltage on the pin. - if all three are set to 255 none of the lights will 
light because the LED will see HIGH on all pins and no Ground path
Numbers closer to zero will cause the color to be more evident. as it
approaches gnd
