I'm going to paint all my possessions that color. Everything.
That will be how you know something is mine. it will be that color. I'm picking a shade that's not too common, and I'll just ask that the few people who have something that color do something about it.
I'll remove the paint if I give it to someone. If I lend it, it'll stay my color, since it's still mine.
I may paint myself that color, too. Maybe not.
The nice thing is that all my stuff will match. I will be very fashionable.
Help or advice is appreciated.
