I feel stupid for asking but I have a ? on Multy color LEDs. I know that there is a power and a ground leg but what about the 3rd or 4th leg on a bi-color led, what gets connected there?
 
there are typicaly 3 leads on these. The center is the common ground. The outermost leads are +Voltage for each color. usually in the 3 volt range.
 
RTFM that came with the LED!

If one leg is longer, then it's common, usually ground.
 
maybe a third color hook up the ground then touch each post with power and see what it does
 
Welcome!

that's a RGB LED?

Then the long one is ground, and the other 3 are +Voltage for the colors. (What Sarver said)

2 leads - Single/Bicolor LED
3 leads - Tricolor LED (middle lead will either be common cathode or anode)
4 leads - RGB LED (longest lead will be ground)

A bi color LED can be made into a tri-clor by applying AC voltage to it.

Technically it is still a bicolor and even though it produces orange/yellow, you can not *easily* mix the colors. For all intensive purposes, tricolors allow one to mix green and red in whatever proportions the person chooses. Bicolors do not.
