I think your question was about transparent pigments, but I think the 
guys answered a question about producing images with transparency.  Is 
that right?  If so:

I think the dark areas you're seeing are where the translucent objects 
overlap (and therefore are darker).  Plus, the high ior value is going 
to give light and dark areas.  When I tried replacing  the partly 
transparent pigments with various opaque colors, I noticed that you 
appear to have some coincident surface issues as well.  Another thing to 
watch out for with reflection/transparency is not having a high enough 
max_trace_level.

Not related to your question, but I noticed you had a godawfully high 
ambient_light setting.  If your scene seems too dark and you're trying 
to brighten it, you probably need to lose the ambient_light and just set 
assumed_gamma to 1.0.  Also, the combination of high ambient_light, 
orthographic camera, and transparent objects with a white background is 
going to effectively kill any visible 3D effect.

BTW, based on the occurence of values like "-0.000000," I'm guessing 
that this code was generated by some other software...?  What are you 
using?  'Cause I really think you might get better results by just, 
well, typing your own code.  ;)

Dang, I'm *really* not trying to pick your scene apart, just want to 
help...Let us know how this goes, OK?
