I also have a pair of Acme samples so they're available too if I need them. They all showed up here right before my Strasburg visit last summer so that's about how far backed up I am on posting random paint color stuff. LOL

Since all three Regatta Red chips I've got are from 1936, here are a couple of 1936 alternative examples...

Duco 6957/Dulux 2336 Chevy Regatta Red is a rather important color since it was used by not only the Lackawanna and the Boston & Maine, but also the Rock Island and the GM&O. On the GM&O, it's the darker of the two reds. On the DL&W and B&M, it's paired with the same yellow.

Regatta Red is also the EMD demonstrator maroon combined with a lighter red like the GM&O and perhaps with that same Reading/Lackawanna Yellow as well...

I think having the Regatta Red chip now to utilize as a reference color should really help out with the dual chip matches especially as they may pertain to some of these other darker reds and maroons. The first ones I tried with the Lackawanna were back on Page 57 using the 1290 Venetian Yellow chip as the reference. There, it got close to either 143 Maroon or 72004 Chevy Burgundy Maroon...

As it turns out, Regatta Red is the same slightly-brownish color as 143 but shaded a bit darker. On the 1954 Bulletin 11 charts, it would occupy the same spot as 72004 if 72004 wasn't there...

Never mind all the Brewster Green hooey I put back on that page and pretty much everywhere else as well but I still believe Erie-Lackawanna Yellow is most likely Borden Yellow and Erie Yellow is most likely Sunshine Yellow... LOL

Volkswagen Saturn Yellow, Ditzler/PPG 81988, is listed as Erie Yellow. Actually, it appears more like it could be Erie-Lackawanna Yellow to me...

Back in the seventies, they also had two different Sunshine Yellows...

Whether or not any of those two match DuPont 93-5607 is unknown at the moment but I did find a nice comprehensive set of VW colors from that time period which should arrive here shortly.

Speaking of VW colors, did any of you guys ever notice how much the paint on Lehigh Valley #126 looks like Volkswagen Sealing Wax Red? There might be something to that...

Meanwhile, the DuPont Regatta Red chip does line up pretty well with the 70-64 GM&O dark maroon plate in the Pullman Paint and Lettering Notebook although not quite perfectly...

Milwaukee Red is the maroon I'm truly after since, according to the Pullman notebook, it's supposed to be the same color as the Lehigh Valley's Tuscan Red but that's proving to be a bit of a challenge right now. General Motors WE5521 from the fan deck is a dead-on match to the slightly lighter DuPont 93-143 chip in the 1967 catalog so I'm leaning toward that one...

Fairly close but I'm not firing up my big fat cigar just yet. Hey, it's tough to find good clean areas on Lehigh Valley locomotives for dual chip matches sometimes... LOL

In the Pullman Notebook, the authors call this maroon color "Lehigh Valley Cornell Red" so that led me astray for a while. It's not the PRR's lighter version of Tuscan Red either as that color is a bit darker and browner.

Besides the Milwaukee Road and Lehigh Valley, the Pullman Notebook also places this color on the Tennessee Central and on the Seaboard Air Line as the Orange Blossom Special maroon.

We do know that 143 Maroon is listed on PaintRef as a 1929 Cincinnati Car Company color but I also have it on a 1929 DuPont Chevrolet wheel and trim color chart as Mohawk Maroon so now we have the automotive name for it also.

Next to Friendly's Ice Cream, New England Motor Freight may be the best alternative example of 143 Maroon although PaintRef lists the company as "North East Motor Freight"... LOL

The image I attempted to attach was invalid for the moment but that problem has since been properly fixed so yes, I am now able to add it later... :)

Volkswagen Sealing Wax Red looks just like the two Socony Reds but with a greater percentage of white added to the mix so yeah, there definitely might be something to that... ;)
