[Silound]

Mine did not come color coded for a bottle, but we figured out it would accept a gold refill can.

However, I fill mine perfectly fine using a small brass adapter a friend has. It's just a tapered piece that sits against the seal and allows you to use a standard butane can. I looked around online, you can fine various ones that are actually made for real Dupont lighters.

Probably another thing I'll buy at some point.
