Engine colors

Did the 63 Chevy truck engines get painted a different color besides the standard Chevy orange? I have a buddy with a '66 (factory 327/th400) and it's painted a greenish-blue color and it's 100% original.

I've got my eye on a '63 C-20 that's been sitting for a long time, and it's 100% complete. It looks like someone a long time ago freshened the engine (283) and painted it a dark blue. I'm just curious if Chevy painted these truck engines a non-standard color from the factory. The blue that's on the engine looks like a darker Ford blue to me.
