Revolution Hypercard cellophane color

[FMoyer at aol.com]

Hi. I wish I could get Revolution's color to work the way Hypercard does. 
Hypercard's color is like cellophane, except for one really neat thing. In 
Hypercard, if you put a colored object on top of another colored object, that top 
object's color trumps everything underneath, and you don't get a muddy composite 
color as you would in the real world, or as you do in Revolution when using 
the admin ink. In Revolution, if 2 "admin"ed objects overlap, a 3rd muddy 
composite color is created. Is there any way to make Revolution behave like 
Hypercard, where:
     black pixels on any objects show through
and
     the top colored object has precedence over any colored objects 
underneath.

Thanks.
