adjust color drawing view

Hi,

I want to use a drawing planview as an underlay to draw some extra's who need attention.

So I want to print the complete reference in a grey color, so new added elements are more visible.
presentation of DV is set to "synchronize view: All settings

What is the best way to have this done?
If I try to adjust colors in the reference properties settings, the display is changed the way I want,
but the colors in the printed (pdf) file are not adjusted
sure, the check mark is checked near "print Adjusted Colors"
what else can be blocking the adjustment for colors

regards Rik
