Here are the readily available colors I considered and ended up using the two on the left for this pack. Notice the light blue looks more blue when not weathered and/or photographed under flash. I might try a slightly more muted/green'ish light blue on the next pack if I can find an acceptable Rustoleum alternative color because I prefer using Rustoleum brand when possible. The silver is Rustoleum Silver Metallic:
I have a jet pack paint thread where I painted both styles at the same time. I know I put a full list in the post............I will see if I can find it.
