OH, I don't know to be honest. I know guys will scorch the pvc with propane torches outside so the fumes don't kill you and then hit it with a spray bottle of water to give it texture as the water droplets will put divets in the stuff. You could probably order black pvc. Think D4katz did one up in black pvc, looked pretty nice. I'm going to just build a huge one for outside the cage so I can drag it outside in the summer time too and let the boas sit on it in the shade while I sit next to them in a chair and read a book or do yard work close to them.
