No question is stupid IMHO

Firstly in the source you posted it is the other way round (but correct)
[0.0 color Black filter 1] [0.5 color Cyan filter 1] [1.0 color White filter 1]

I get (official3.1 & WMP0.6a) an object that is white with a little cyan noise

Could be to do with the fact that in colors.inc #declare Clear   = rgbf 1;//White with
a filter of 1
I don't think media uses the filter/transmit value & it doesn't affect the results I
got
So basically you might as well be using
[0.0 color White] [0.5 color Cyan] [1.0 color White]
instead of
[0.0 color Clear] [0.5 color Cyan] [1.0 color White]

Hope that helps
