Here are some thoughts on the subject of colored paper:
My degree is Environmental Science with a minor in Forestry. When I was in
college, I visited a large paper mill and observed the paper dying process.
The mill showed the vats used to dye the paper and then showed the water
after treatment to extract the excess dye and other chemicals. I was amazed
at the clarity of the water. I would have to say that at least the larger
mills do a terrific job of ensuring impact to the environment is minimized.
I can't speak for all printers so you have to draw your own conclusions as
to how environmentally friendly printing operations are.
