I saw the New Dreyfuss at Eastside Trains in Kirkland WA (They easily have a hundred engines in their display shelves, most are O-gauge). I loved the look of the engine! Unfortunately, my layout has 54 inch curves so the Dreyfuss is too big for my layout.
I did find the the article on the colors in the NYCHS web site.
New York Central System Historical Society, Inc.: NYC Colors (nycshs.blogspot.com)
I thought that the article was well written.
The article has pictures of the dark grey and light grey on 4' x 6" metal plates as well as the paint chip codes for Sherwin-Williams oil based paint.
I am purposely not giving my opinon on the shade of grey used, however the author of the article, Thomas Gerbracht, started with "I feel like the guy who just bought a second watch. When I had one watch, I knew what time it was. Now I am not so sure…"
Thomas has 8 points in his conclusions, #7 is:
"If you are viewing these color samples on your home computer, some or all of the color images may convey an incorrect impression as to the veracity of these results. This is due to the different specifications of each computer monitor manufacturer, amibent light conditions, and many other factors. You will have to use the formulas to exactly match the colors described and photographed for this article."
I am not looking to restart the debate, I do not want this thread to get deleted, just providing a resource to look at for additional "color" on the situation.
