You know, the subject title may have obscured the original intent, but the idea of finding a safer coloring system is worthwhile.

With wooden props we may already be fairly safe.

Synthetic props probably should have something better than paint. At least something that sticks better. You see MAs all the time with the paint worn on the LE.

But I'd like to suggest that from what I've seen at my flying fields is that it would be a really good idea right now, if APC would change the color base of their razor sharp props from that almost perfectly invisible, almost perfectly neutral gray, to any color that would be more visible. They not only have the most lethal looking knives out there, but their choice of base color is awful when visibility is the issue. It's almost like they worked at making them invisible.

Now.... how do we get them to make their stuff safer?
