Trying to figure out what's wrong with my greyish Stephanie 4 eyelashes, 
I just found a flaw in Poseray (version regarding handling 
of image maps "plugged" into the Diffuse_Color root node input, when 
there is a non-white color specified (and possibly also otherwise):

Poseray translates these as the image map layered /over/ the Diffuse 
color - even when the texture is fully opaque.

However, the operation should actually be a /multiplication/ with the 
Diffuse_Color value; I think it can be modelled in POV-Ray as:

     texture {
       pigment { ...TEXTURE... }
       finish { ... }
     texture {
       pigment { color COLOR_VALUE filter 1 }
       finish { ... }
