The pigment was raised to 0.98 (as stated in your 2nd message at p.b.i.) and it
was okay then, am I understanding this right?  If that's all then it's a very
nearly clear texture whereas before it was not.  Anyway, it's always seemed to
me that semi-transparent textures ('transmit' especially and visible spotlights
such as through the old 'atmosphere' of v3.0*) shouldn't be brightening the
background.  But I still have not checked this against reality very well.  Now
media is easy to darken the backgrounds of visible spotlights by using
'absorption' so that's not a problem anymore.  Textures on the other hand might
still be doing this.
