That's not what happens in Hypercard. In Hypercard, the color of the top
object trumps everything underneath unless what is underneath is black.
Any other color is completely obliterated. There is no blending. So blue
over a white
background remains blue. With "blend" in Revolution, I believe blue over
a white background becomes light blue.
Perhaps there is something that I don't understand about blend.
The thing you're missing may well be a property called "blendLevel", which basically defines how opaque the top graphic is.
Fred and I talked about this in email a while back. I don't think Revolution can do what he wants. The reason is that AddColor was an add-on, an overlay of which HC itself was completely unaware. AddColor has special color effects that no other graphics program allows -- specifially, it allows various blends or opacity to operate with its own graphics, but it *always* allowed black pixels on the card layer to show through no matter what graphics effect it used for itself.
Thus, when using two "opaque" addColor objects, the top object would cover the lower one and there would be no color blending between the two. However, when laid over the card, all of HyperCard's text or native paint images *do* show through. It was possible to have an opaque addColor object overlapping both another addColor object as well as a field, for example, and the opaque object would cover the other addColor object while still allowing the field text to show through.
When color is implemented natively, as it is in Revolution, the blendlevel or opacity applies to the entire card with no exceptions. There is no way to make color objects opaque to each other but not opaque to black text or graphics. And that's what Fred wants to do.
