Not really. Transparencies subtract some colours from the
transmitted light; prints subtract some from the reflected light.
Displays make their own...


Ah, so that is why they are backlit then?

So they can 'make their own?
What a prat. An LCD display IS a color transparency.


No it is not!

A transparency is a subtractive process.
An lcd is additive.


Um, this sounds a little confused. The important distinction is between
*additive* colour (eg; RGB) vs *subtractive* colour (eg; CMYK).
With RGB, you're *filtering* a full spectrum illuminant, with CMYK,
you're *absorbing* part of a full spectrum illuminant.
