Non additive translucency?

Sorry not particularly great at graphical stuff. Thanks for any answers.

I’d like to the translucency here to be non additive. Its a series of nested spheres forming the series of bubbles. But I don’t want the translucency to add up. I know I can get one solid non additive solution via post processing but I ran into troubles there as well due to not knowing how to superimpose the smaller spheres on to of the encapsulating ones.

Does anyone know if there’s a way to make translucency non additive?
