I figured it out.
Here was my solution or one way to do it. I wanted to print a black and white pdf with the R/W line being a red color.
1. I created a new pen table. (In the print dialog, click >> Resymbolization >> New Pen Table >> Save (A modify Pen Table dialog appears).
2. In the "Modify Pen Table" dialog, Click Edit >> Insert New Section Above >> Give it a name (Non Color)
3. In the "Element Selection Criteria" tab under "Color option, specify the range of the color from the color table you want to stay non-color. Exclude the one you want stay color (67).
4. In the "Element Output Actions" under the "Color" option specify it "By Index" as 144. This is the grey color you want everything to be except 67 which is naturally Red.
5. When you print, Make your set the color option as True Color and you new Pen table with grey out everything except the color 67.

You are correct Lorys. At the time I thought It was a simple question and didn't want to spam the board. I had asked another question that same day I think. :)
