Hi Oliver,
Your original color encoding should work OK too - and does for me with
v3.7 and v3.8 versions of POV-Ray on Ubuntu linux.
(jr, does his original scene not work for you?)
One thing happening here is I believe the sphere is partly, or wholly,
lit through the plane. You could try adding finish { emission 0.3 },
say, to the sphere to make the transparency more obvious.
If still no sphere visible, try explicitly deleting the plane.png file
ahead of running the next render to be sure you are really creating a
new output file and not looking at an older one perhaps created with Red
and Green out of colors.inc.
Oh, and I don't know how the mac version saves ahead of each render. I
understand some versions have user interfaces with editors? I guess I'm
saying, be sure your updates are being saved ahead of new renders.
