I was thinking that.

Or better yet, get with your neighbor(s) and swap some, make some new combinations that aren't currently shown anywhere else. Be creative. Maybe even check the hardware stores, get some similar reflectors of different colors. Add a purple one.

Ding ding ding! That's what you do when dots start showing up on your stuff that you didn't put there.
