…..: Red paint.
The point for the day is to remember that your sense of smell can be very good, 
or very misinformed depending on what you’re smelling (and who you are).
Sulfur (sulfur dioxide) can be smelled when it’s as low as 0.009 parts per million (ppm). The exposure limits are at 5 ppm. There are many chemicals that work just the opposite.
Before you make an assumption, figure out what you are smelling.
