CB&Q paint colors - Red and Gray

[BLW ENGR]

 I would like to find out what "gray" is correct for CB&Q locomotives painted in the Chinese red scheme.

 

The red is almost orange, or so Sherwin Williams indicates (no, I'm not using it for models).

 I can't seam to find a specification for the gray.

  The CB&Q listed it as 'Chinese Red', IIRC.  The Duco number is 254-4182.  The grey on the roof is tougher.  UP 'Harbor Mist Grey' is too dark, and most 'M-O-W Grey' is too light.  What is Sherwin Williams using for a 'base'?  The red is a very bright red!

  Here is 'mix' formula for Floquil paint:

Chicago, Burlington & Quincy

                  Aluminum          4  parts   R-11  Reefer White
                                          1  part     R-12  Light Gray
                     
                       Red             5  parts   R-187 Socony Red
                                          1  part     R-11  Reefer White

                       Gray            9  parts   R-150 D&H Gray
                                          1  part     R-11  Reefer White
                                          1  part     R-10  Engine Black

  Somehow I  think the black sort of 'zeros' out the white - maybe D&H Grey would be good(but I feel it has a little 'sand' or beige cast to it).

THis question comes up a bit on the CB&Q list.  Even between the "Blackbird" and Chinese Red scheme, the greys appears to be different.  I've touched up the grey area using SP Lettering Grey mixing is as appropriate to match the manufacturer's color using white or SP Lark Grey.  After weathering, everything blends pretty well.

 Sherwin Williams has this:

Chinese Red SW 0057

 I had it color matched at Lowes and although it looks "orangish", it looks like the same stuff that IRM is using to restore SD24 #504 (see pics at their site).

The original GE drawing (used for the U30B's & C&S U30C's), dwg # 41B511706, calls for:

Gray  -  Lucite    Dupont #890-93879

Red  - Lucite      Dupont #890-93880

White  - Lucite    Dupont #890-93881

Black  - Lucite     Dupont #890-67104  (Edging on foot boards)

Black  - Dulux      Dupont #88-005 (Underframe, Trucks, Fuel tank)

I have an E-mail into them to see what records they might have.

Floquil and Scalecoat2 are the paints I use. I'm oldfashioned I guess but I prefer solvent based paint.

For Floquil CB&Q red I used a mix of 70% SP Daylight Red/30% Caboose Red

Floquil CB&Q Grey was a mix of 50% Refer Grey and 50% SP Lettering Grey

Scalecoat2 makes a CB&Q Red that is reasonably close. I added about 10% SP Daylight red to it.

Scalecoat 2 EL Grey was used for the grey
