Where should I get white foam. I am considering buying some beige foam, unless I find some decent white foam that is not too expensive. Where do you recommend buying white/colored foam? (besides Kane's red foam)
Well, I went for painting the backs of the darts. I used neon orange paint and primer, they came out really well, and are a lot easier to find. It was also pretty fast to do. A small disadvantage is that yes, some paint will end up in barrels and plunger tubes, but that can easily be cleaned out every six months or so when you clean/re-lube your guns. I would like to see a picture of Ivan S's permanent marker colored darts, that could also be an alternative.
Edit: Here are my completed/painted darts, I used a primer, and neon orange spray paint.
