Oh... Okay, hold up. So you're using the actual "Tracing Paper" tools ArtRage has. I sometimes forget about the "Tracing Paper" option, because I'm so used to using layers in other programs for this.
Personally, for what you're trying to do, I don't think the "Tracing Paper" would work as well as just importing the image and drawing over it on a new layer. When you use the "Tracing Paper" it covers over your image (which is now why I think your lines were looking gray) until you chose to hide the Tracing Paper (by hitting the "T" key to toggle it). You'd also have to make sure you weren't using the "Choose colors from tracing image" option, otherwise you'd be using the colors of the pixel your brush was over at the time you started the mark. Getting the image to be the correct size would be troublesome also.
If you go with my original post, all you have to do is change the layers canvas settings to make the textures you'd like, then once the image was traced, set the grains "Opacity" (do not confuse this with the layers opacity) to 100% to show the paper. As for stencils, they're quit useful if you plan to color and shade your images. Once you block in the color, you can make a stencil from that colors layer and shade on another layer without having to worry about going outside the lines (LINK1, LINK2).
Nothing is easy to the unwilling.
