I won't know until I try :-)

While that's certainly true, I guess even with rgb-specified colors it 
will already do some good to scenes with colored transparent objects, so 
that e.g. two orange filters in sequence won't necessarily exhibit a hue 
shift towards red, but could retain the orange hue while just gaining in 
saturation.
