I scan my documents in color.

The problem with printing it with a color printer would be duplicating the pink color of the background. What you see on the monitor is hardly ever what the printer does exactly unless you have a really well tuned system.

I think in the long run it would be better just to convert the image to black and white, then print on pink when you need it. If you never need a copy, then you don't have to worry about it.

I don't think paper weight makes any difference either. Once you laminate it, the thickness of the paper is moot. Go for similar color and just do it.
