We entered the carwash that we usually use, but haven’t been to in a while, and found a sudsing ambiance of green! That was a surprise.
Then as the car was rolled along it switched back to the usual no color, and I thought maybe they were trying to suggest it was a “green” car wash.
But no, after that we had lilac, bright blue, and red, and so on. Maybe it’s a rainbow message?
