As a follow up to Bob's remarks on L&N boxcar red, it varied. L&N would ask paint suppliers to bid on paint. There was a sample provided, I was told. L&N was a frugal railroad. A better price meant more than the paint being slightly more or less red. Not to mention that in the early 20th century some things were somewhat less standardized than today. Oxides of iron and red lead were primary pigments and proportions could vary from supplier A to supplier B. Some weathered at different rates.
In short, just take it that all L&N red freight cars were NOT the same color. Not nearly.
