I can't say for sure, I've never actually signed up for Facebook and a lot of those pages require a login to see their content. The colors are guess work sometimes, but I do my best. The videos on YouTube credited to Julian Buesink of various races from the 50's have been a great resource as they're pretty much all in color. They're pretty blurry sometimes, but if there's a b&w photo of a car in one of the videos to be found, the details can be pieced together that way. I try to be as diligent as I can with this sort of thing, but sometimes things like car/number color, sponsorships and contingency placement require educated guesses.
