Each of the graphic effects has an array containing all it's settings.
Each of these arrays has a "color" element which can be used to turn
the effect on or off. The other elements vary according to which
graphic effect you are using, but none of them will have any effect
without a color. So to do what you had on mind, try this script:

on mouseEnter
  set the colorOverlay["color"] of me to "red"
end mouseEnter

on mouseLeave
     set the colorOverlay of me to empty
end mouseLeave
