Well, I must say that all I can tell is they are deeper green than the commons. The pictures of Green Dragons that I have seen are a deeper green and not so red. However, I will say I have a hard time telling if something has more red or green in it at times. I am somewhat red/green and blue/purple color blind (sigh). Makes things appear different to me.
The Green Dragon traps are much darker in the center than commons. I might put it a deep purplish green. When my wife gets home, I will have her look at them.
