Those are U.S.A. Stars
Sounds like you are looking at the constellation Orion, one that's easy to see in the northern hemisphere winter night sky. I believe JeanaMai has the right reason you never noticed - you don't pay attention to the sky. The blue star is Rigel and the red one is Betelgeuse. One of the white stars is Bellatrix, or beautiful warrior or as I like to think, the FemDom star.
You must be looking at stars imitating the American Flag. They must be over the Us.
I think you're looking at the flag. I don't know.. maybe not.
ALL the planets are aligning for the once in 26,000 year conjunction- it's a once in a very long time event that the ancient Mayans calibrated on their long count calendar. Enjoy it- it won't happen again for another 26,000 YEARS!
They are someone's Christmas decorations. Put your glasses on.
