You wouldn't believe how hard it is to find spray paint around here. Seriously. A lot of places don't even carry it any more because of all the kids huffing it. :( Sad.
...And rather frustrating for me! I need that crap for like...you know...what it was INTENDED for? Anyway, here's what I've managed to find so far! That's red, blue, royal blue, purple, gold, and black...all metallic. :) The Krylon says it's safe up to 600 degrees F, but the other one says only 200. I think that kind will still work though, on these particular lamps. They only have 30 watt bulbs (perfect for a goo kit), so they never really get that hot.
