I saw a Need for Green 2019 GT this weekend in person. Here, in Michigan, it was cloudy and rainy all weekend. The color looked like John Deer Green, just like some of the photos on here. I was told, a month or two back, the color was more like Signal Green on the Porsche and BMW’s. Maybe in the sun, but after seeing the color, its hard for me to fathom. I could be wrong, though, because some of the pictures show the car in direct sunlight and it looks more like Signal Green.
The car I saw looked exactly like the one in the Ford Garage photo and the first picture in this thread.
