RGBLed polarity

[alandmoore]

The RGB LED that came with my arduino kit is reverse polarity; that is, the common lead is actually Vcc and the individual color inputs have to be pulled LOW to turn on. I don't know if I have a weirdo defective LED or if this is a common thing.

If it's the latter, it'd be nice if we had a switch to reverse the polarity of the RGBLed object so that it pulled the pins lower to make colors brighter for LEDs configured that way.
