Paint color Q on a 72

I am buying a 72 BUT the color appears to be rally green and is the original color of car. Is this possible??? Or would it be a custom color ordered for the car??

What is the code on the firewall cowl tag?

THere is no Nova in 72 that came Rally Green originally. What is the color code? I see 3 greens in 72:

36 = Spring Green
43 = Gulf Green
48 = Sequoia Green
