The metal stars you see on the outside of houses and barns — most commonly found in the more rural parts of the U.S. — actually have a deeper meaning.For one thing, those particular stars have a very specific name, depending on where you are.They can go by Amish Barn Stars, Barnstars and Pennsylvania Stars.
Some think the stars were inspired by Chinese good luck stars.The Pennsylvania Dutch also considered the five-pointed star to be a symbol of good luck.apparently the color of the star denotes a specific meaning.
For example, blue stars signify protection and green stars symbolize fertility and growth — ideal for a farm.Most homeowners or farmers who have one have probably never given it much thought, but other people certainly have.Distractify credits a 2007 thread for initiating the rumor that the stars mean the homeowners are swingers, a term used to describe couples that “swap” partners.this barnstar meaning is likely to be false.
More likely, it’s just people who enjoy what the star stands for, or just think it looks good on their house
