HealthArmor makes colors of your armor change depending on how hurt you are. That's it. Any leather armor that has "HealthArmor" as the first lore line is considered health armor.
This plugin is just an idea I once implemented in CommandHelper and forgot about it. I could not quickly find a simple plugin that does that so I made one. It is compatible with several MC versions to the past, and should also be future-proof. Enjoy!
