What color code of blue was used in 1911 on Fords?

[oldmotorsguy]

According to the info I dug out of "Model T Ford - The Car That Changed The World" by Bruce W. McCalley, all Fords were painted a very dark blue in 1911.

I am currently restoring a 1911 Ford Model T Roadster with a mother in law seat (Ford labeled them as a 3-passenger Runabout). The color specifically called for by McCalley is "a very dark, all-but-black, blue."

What paint manufacturer and paint code would come closest to this description, according to the majority of Model T nit-pickers (of which Fordbarn has a quorum)?.

This image (if I loaded it correctly) looks right to me, but what do I know. Where can I find this stuff?
