How the price of paint is set in the hearts of dying stars
Yonatan Zunger

Well I for one learned a bit more about how colors happen as they are formed and how and why stars form and decay at the molecular level. but I’m not sure farmers and ranchers paint barns red as a result of economics. A sealer without pigment would be even cheaper and would do what its intended to do. Protect the barn. And why then are many farm houses white?

Maybe we should dig deeper into this pressing issue. ;~)
