Truck was painted in a fleet colour, so you'll have to find out which company originally ordered it to find out which green it is. It's a long shot, but I remember Bell Canada using vehicles in a dark green.
I worked at the Oshawa plant for 30 years, and I remember certain fleet colours coming down the line. Depending on the size of the order, they would paint those vehicles all in one large batch. One colour that I remember was an orange that I believe was for CN Rail, but was not available for purchase to the consumer.
