No, actually I found that having a little bit of color actually helped release the paper better on the fine traces. I look for a light color background because most of my boards are 2 sided and it's difficult to align the pages when you can't make out the crosshairs against a dark background. Thin works great, haven't tried the magazine covers. What you need is a quality publication -- most catalogs are recycled paper and have a kind of grainy surface. You can tell by rubbing your thumb on a sample under water. The recycled paper will particalize differently than the better quality one. National geographic, TIME, 4 wheeler, geo world, sharper image catalog all work pretty well. Also, its best if the paper hasent been handled before use (no collecting these from dentist waiting rooms!).
