I painted my wall a neutral gray, SW Unique Gray in a flat finish. It looks similar to what you have. I often wondered if a mix like black widow would be better, but the finish I got with the gray paint was so good, I didn't want to muck it up. Since then, I upgraded from a 1000 lumen projector to a 3200 lumen Viewsonic PJD7828HDL, and I haven't given an upgrade to the paint any thought. If anything, I might consider a darker shade of gray since this projector is so bright. I have compared to a couple of professional screens, and the image was more washed out on one, and looked good on the other, but there was a minor issue with glare.
