Hi there!
I agree Plus the fact that when you get the weights in script, xsi list also the effector weights(equal to 0) but they are there, and complicate everything when you want manipulate envelope weights value.I finally found more easy to parent nulls to the bones and envelope to the nulls.

>  No I know that.  But you can't envelope someting to an effector so why would it change color?  The root is part of the chain but doesn't change color.  You are only assigning the bone as a deformer so only that should change color.  I'm speaking strictly about the display property, not about its relationship in terms of mechanics or anything.
