color

Is there any standard color code for magazine tape to differentiate fmj, jhp, green tip etc? I'm planning on starting a thin strip of colored tape on all mine to tell at a glance

I have two heavily worn magazines for my pistol that I would like to paint. They are all steel hard anodized Sig magazines. I would like to colour the magazines bright shiny blue so I can instantly see them on the range. I do a lot of run-and-gunning and have stepped on them, walked past them...
