What's a Microcontroller text clarification

Hi- Just beginning to explore the basic stamp. On page 62 fig 2-17, I get the green LED when I wire pin2 (shorter lead·and flat side of LED) to ground. I get the red LED when I wire pin2 to +V. Is it possible the bi-color·LED that came with my kit is different from the one the text was written for? Or is the text incorrect?
Thanks

    Clearly the LED you have is connected backwards from what's described in the text. There's no "standard" for bi-color LEDs although manufacturers rely on the datasheet for the device they buy to determine how it's connected. I've seen other texts where a bi-color LED is described as you've observed. Maybe Parallax got a batch of mis-labelled LEDs.
