1955 Elto paint colour - what matches?

[TN-25]

I was wondering if anyone happens to know the correct paint colour for a 1955 Elto 5. I was talking to Peter McDowell at North York Marine last weekend and he told me that he has correct paint for the 1956 Elto, but not the 1955 unfortunately. Elto of course was Canada-only at that time, but really is just a Gale motor sharing the cowl trim with the Montgomery-Ward Sea King, then having the Elto script, maple leaf and beaver emblems.

Looking at my motor and a few other 1955 Elto motors, to me the best match I can guess is the 1967-68 Evinrude small motor medium light blue. Does anyone happen to actually know the secret paint match?

Attached are 2 samples from my 1955 Elto and finally a survivor 1968 Evinrude Mate 1?-horse for comparison.
