[SEL] Engine colors

[George Best]

I know that the shade of color used by some manufacturers would vary
from time to time since some bought their paint from whoever gave them
the best deal, or it could vary just because someone different was
mixing the paint.

However.... Were there any manufacturers that didn't have a specific
color which identified their engines?

As an example, I've heard that Samson engines made in California were
painted various colors depending on what they had on hand.  Anyone else
heard this or have information on this?
