If you have a green dot, you are consumed with money, and therefore, a capitalist pig that must be shot.
If you have a blue dot, you are against clean air and water and will be sent to a re-education camp.
If you have one of every color, you are homophobic and will be sent to the rainbow camp of endless sodomy until you embrace your inner child.
If you have a red dot, you are already a socialist and safe.
Perhaps your HOA is grading how you take care of your home.
Another possiblity is a bunch of street racers are marking
your street with reflectors to race at night. ;-)
