This absorbing media should be red _and_ produce a red shadow. Isn't that so
then?

Filter and transmit have no effect on media. The transparency of the media is
controlled by its density, which in turn is controlled by the rgb value. The rgb
value can be anything, it's not limited to the 0-1 range. For example
<27,100,100> is the same colour media, but much denser, i.e. less transparent.
