The Fritzing diagram makes it look nearly impossible to tell the pins of the RGB LED apart, but it really isn't! The longest leg is ground. The single pin to one side of ground is red, and the other two pins, moving out from ground, are green, then blue.
If you're using the flower, rather than a standard RGB LED, be very careful if you use heatshrink over the connections -- it's very easy to melt the flower petals with a hot-air gun!
