Scripting Graphic Effects

[Judy Perry]

Hi,

I am confused with respect to scripting graphic effects.  In the property 
inspector, they can be boolean (you check them or you don't; once checked, 
you can set other attributes, or not), but the docs present it in terms of 
an array.

What I would like to do is set the colorOverlay to a color value on 
mouseEnter and then TURN THE WHOLE THING OFF on mouseLeave.

Seemingly you cannot set it to false... would the answer be changing the 
HSV value?  What is the color value of no color overlay?  0 saturation? 
Hmmm... no, that didn't seem to work.  Am clueless!

TIA,

Judy
