It is not realistic, but I was able to mathematically predict the result,
and it worked.

When the transmit value is below 1 (even when it is below 0) POV-Ray uses a
certain formula to calculate which color is seen. All I'm asking is that
that same formula is used when the transmit value is above 1. That way,
although the result wouldn't be realistic, you should still be able to
mathematically predict the result.

To those who are able to look in the source code of POV-Ray:
Does it make sense what I'm saying?
