One would think so, but you'd have to also take into account the type of film used, and what if any emulsion takes place in the exposed photo.
Besides, using a simple black and white test as this would allow for a higher margin of error, one could other colors that would give the same result in straight B&W.
As I mentioned before, the photo method simply is not going to work. It is lazy research, there needs to be an eye witness account, a note on the back of a photo, a color photo or SOMETHING. Simply staring at a black and white photo all day is going to trick your eye into seeing what you want to see.
I've been down that route before many times.
I am currently working on digging up some info so we can know for sure what all of the 4 K classes were painted as "delivered". This may help shed some light on things as the Grande was typically very consistent as far as paint was concerned.
So far here is what we do know:
I grabbed the following blurb from Utah Rails.
Jerry Day has shared a letter dated January 23, 1926 to all roundhouse foreman under the jurisdiction of the Alamosa Division, which includes a line entry for "Russian Black Jacket Enamel for jackets." Much discussion has taken place as to exactly what color "Russia Black Jacket Enamel" really is. Some say it literally is black. Others think that it is similar to Pennsylvania Railroad's "Locomotive Black" which is actually a very dark green better known as "Dark Green Locomotive Enamel," also known at times by Pennsylvania fans as "Brunswick Green."
As I stated in a previous post, this color was very simply a mineral black, a greyish black.
We then have the standard paint practice which seems to suggest that Green became the standard in '37. However the question was raised before, what exactly is this the standard painting practice for? Does this include NG locomotives? What we're missing here is the piece that ties this all together at this point.
As I mentioned to Earl, I like the green and I hope evidence comes to light to prove it once and for all. Sadly right now we've got a few miscellaneous relating to color and conflicting first person reports.
This has always surprised me considering the rest of the D&RGW has been run over with a fine tooth comb.
