Swatch control in transparency effects

Question

Does Adobe have any plans to incorporate swatch control in transparency effects? What I mean is, say you want transparency effects to affect all but one swatch. And where it interacts with that particular color - no effect. Or, the opposite, have the transparency affect ONLY one swatch, and ignore other colors.
To have a feature like this, the document swatches would probably have to be listed in the effects dialog, maybe with check boxes to turn swatches on or off. I think a feature like this would be very useful.
To see what I mean, draw 3 boxes on an InDesign page, make all 3 overlap. Color one cyan, one magenta, and one yellow. Bring magenta and yellow both to the front, and set to multiply. Make sure magenta and yellow only overlap within the area of the cyan (refer to the image). There is green overlap, blue overlap, and dark brown. The brown is where all 3 overlap. Is there a way to make the brown area red - and leave everything else the same? (The red would come from yellow and magenta being multiplied, with no cyan not participating).
Do this without a pathfinder command, or drawing a red box, or a white box to KO the cyan, or drawing any extra objects or changing the exiting shapes. If there is no way to do it, then OK, I didn't think there was. But if some sort of color or ink control is incorporated in the future it would be possible. Transparency is applied to objects and groups. Why not extend the capability to colors as well? It would add a new dimension of control.
In the example, if the cyan swatch was excluded from the transparency effects, the brown area would be red. No extra artwork added, no modifying the existing shapes.
If you group the yellow and magenta, and isolate blending, it's true the red color is achieved. But the green and blue overlaps are also eliminated. I want to know if it is possible (or ever will be possible) to selectively control document swatches in a transparency context.

Answer 1

Maybe listing swatches with effects would create too much confusion. If it canceled transparencies, people may get frustrated trying to figure out why the transparency has no effect on an object, when in fact the negated transparency is being caused by the underlying object's color.
Setting aside the swatch idea for now – what about something much simpler, and much more attainable? Is it possible to add a feature that makes an underlying object "immune" to transparencies of objects on top of it?
This would be one simple option that could be enabled. The result would be this: any blend modes on top of the object would not affect the object. They become normal blend mode in relation to the specified object. A simple knockout. (Drop shadows could still exist on top of the object of course, but they would not multiply)
You could go a step further and split this option into two, one targeting blend modes, and the other opacities. The blend mode would probably be the more commonly used - making all objects on top knock out, with one simple command.
Basically the object won't allow transparencies above it to interact with it. It would eliminate the need for modifying the objects shape, or creating additional objects to achieve a knockout.
In the case of the 3 blocks, the cyan would be assigned "immune to transparency effects". So the area where all 3 boxes intersect becomes red. A very simple solution. I think people would use this feature.
How do you go about getting Adobe to consider adding something like this to InDesign, or other applications?
