RGB LED Common Cathode versus Common Anode

I got so antsy to want to control more than one RGB LED, that I went to radio shack and saw they had a "full color" led. I thought, yay, this looks exactly like the common cathode RGB LED that came in my kit, I'll take 3... Long story short, the wiring for the 2 do not seem to work the same, and all of the info I am finding points to using PWM pins for common anode rgb LED's.
