1925 Cobalt Blue

[dibarlaw]

Does any one have a formula for a close match for the 1925 Cobalt Blue. I was able to get the 1925 Brewster Green matched by a chip that Hugh in Texas gave me. I used the information from the 1971 AACA  Antique Automobile Buick Article by Dave Chambers. The matches were for car colors that were already 20 or more years old. Also, they were for the Duco or Dulux formulations. The PPG numbers gave me a good dark blue on the web color match sites but our local paint supplier does not have a cross reference. So I would need a formula or a chip of paint to scan into their equipment.

1925-45 with mostly original Cobalt Blue.

Larry, without digging out Dave's article(s) in the Antique Automobile magazines, our 1922 Model 48 has been labeled as Cobalt Blue or Buick Special Blue.  Do you think that this is the same shade of Blue that you are inquiring about?  I do know that back at that time certain models of Buicks were only available in certain colors.  Our 1922 Model 48 was only available in the Cobalt Blue.  Jim Milewski's 1923 Model 48 was only available in that very beautiful Maroon paint color.  The Sport Roadsters and Sport Tourings were only available in certain colors.  I wish that I knew how long this practice was used, but, I simply do not know.

Terry :

 In Dave's article he shows that each year the cobalt blues crossed to the more modern, non metallic (post war) close matches..

   Original color                                                     Substitute                               Ditzler (PPG)#              DuPont#

1921-1923 Dark Blue       Color Var.     1952 Studebaker Nocturne Blue           10989                       93-57068

1924 Cobalt Blue Med.    Color Var.      1954 Ford Sheridan Blue                       10428                      246-81501

1925 Cobalt Blue             244-3198       1953 Chrysler Huron Blue                     10027                      246-81580

The 1953 Chrysler Huron Blue showed up as a very light blue.  But, the #s Dave gave for it are for a 1941-1951 Chrysler Newport Blue.

 Looking at all these cross referenced blues each are a different shade when compared.

The 1925 Limousine Blue  244-787      1949 Mercury Alberta Blue                     10480                       246-55106

Looked even darker when compared to the others on the web paint cross referencing sites.

1924 Model 49 should be Cobalt Blue if correct and I really like the color.

1924-44 also to be Cobalt Blue that sold on e-bay last year.

I have the formula for Cobalt Blue in modern PPG Global DG.

In the early 1970's my 1926 Buick was painted with Nitro Cellulose lacquer from the Cobalt Blue formula supplied by Dave Chambers. When I restored it again in 2008 the PPG rep. shot it with his color matching machine and the new formula in Global DG was the result. It is an exact match. E-mail me at bobatkinson@roadrunner.com and I will be happy to share the formula with you. Since it is a custom color it is not cheap but it was worth the price to me.

Attached is a picture from right after it was painted.

Bob:

 Thank you. This is the color I could really see the car having. The former owner painted the car in lacquer in the early 70s. A medium/dark blue. Not as dark as the cobalt. Then in the early 80s he repainted over top of the darker blue in what I would call "Earl Sheib Blue". I could have lived with the darker color but not this light blue.

Larry,

I got to thinking about Cobalt Blue and getting a sample.  One place that would have little if no fading would be the underside of the cowl vent.  There are only 4 small bolts that hold this part in place.  I wonder if you could get someone to have theirs colormatched, or would allow you to borrow it?  Or can you send a sample to someone to verify a color you are considering.

 

The other comment I wanted to make is the number of cars that Cobalt Blue was used on.  According to the BCA judging manual, several models over 3 years.

1924 models 37,44,47,48,49,50

1925 models 27,28,40,44,45

1926 models 20,26,27,28,40, 47

 

I appreciate all of Dave Chambers contributions, but I do know that his recommendation for Brewster Green was not correct when compared to my original paint that was under the cowl strip and the firewall ID tag, so he may have been a little color blind.  I can only speak for this 1 color.

Put the photos you have in power point or photoshop and overlay the blues

Here,s a list of matching Dupont colours

Remember too that the same colour sprayed at different pressures and even different humidities  can/will/may dry to different shades.  When I worked at a GM dealer in the sixties one of our painters mixed a current colour and painted six different shades on sheet metal that had all been prepared the same.  Add to this 85+ years and some of our faded memories.  It really is nice though to at least try to come close to the original colour.

By the way, I could live with any of these blues rather than the non original green/green that is being discussed on one of these topics.

Larry,

This is the mixing formula for Buick Cobalt Blue that Bob Atkins used.

PPG Global DG Formula:

D700 16.9

D704 122.2

D702 84.3

D736 91.0

D724 774.3

 

Also attached is the Cobalt Blue Formula that Bob Bitowski used.  I believe this is Sherwin Williams.   He started with Bob Atkins formula.  Hugh
