Ferguson Script Color

What are the AUTHENTIC colors of the Ferguson script logo, and Ferguson systems logo (era 1951)?

The Ferguson script logo around 1951 was navy blue. It was also seen in dark green when the TO-35 came out in late 1953. When the Ferguson 40 came out, and the TO-35 colors were changed to Bamboo Beige/Flint Metallic Gray, the script was often seen in red.

In the days of the Ford Ferguson 9N/2N the Ferguson logo was often shown in a light green, sort of a cross between pea green and mint green.
