If your circles were strong solid colours you might even be able t= o set them up in a precomp with an add blending mode, then key the resultin= g colours to create mattes for the various blending modes you want in your = main comp.

It would still get fairly complex, and I'd be inter= ested to know why you wanted to do this. =A0I would have thought that blend= ing modes by themselves would be able to do what you want.

How would I go about creating a &quo= t;conditional" blending layer? What I mean is it possible to have say = five circles called A,B,C,D,E randomly floating in space and overlapping, s= uch that unless A is over B, A has "normal" blending mode, but wh= en A overlaps B, it has an "add" blending mode? And then when A o= verlaps C it has multiply blending mode instead, just as an example? This i= s a puzzle...
