Anything to keep the reflection effect down. I have a olive color. If you're going with a FP, the paint you choose to create the screen is the real decision. I went through a grueling 2 months of painting and re-painting and testing -- I started feeling OCD with the paint roller. Anyway, I learned alot about the appropriate paint to use for your screen as well as how to wet sand paint from drywall... how to get that smooth as a baby's @ss effect before priming. My wife thought I was nutso, and she's probably right. But, my patience paid off, I now have a huge screen that only cost me the paint, and my time. Plus, the size I wanted wasn't readily available from the typical screen vendors.
