one of the packs had 2 orange ones so I decided to try them.
That's basically what I usually do. I don't smoke either, but when I see a pack with all the right colors, I'll grab it. Usually yellow, orange, and/or white. I like the white ones because it's easy to see how much fuel you have left, but on the other hand....in winter they can be hard to find if you drop it in snow.
