sounds good, usually 2 color LEDs have three legs of which the center 
is ground.
maybe you get a better signal on the other side of the resistor that 
feeds the LED

probably you find a concrete instruction in the LD archive since I 
usually try to make such tricks available when I discover them... but 
this may be the less fun way :-)
