That light grey color next to the matte green is actually the Lunar White / Ghost White that is the special Edition 1 color for the truck. It’s a multicoat or pearl coat metallic and looks a bit more grey here than normal, which it can definitely look like that in the right lighting. Although, it’s a difficult color to get right on camera... In most shots of the reveal truck it tends to show more as plain white or even a bit yellow or whatever color it picks up from its surroundings. They do have a light grey that is non-metallic, next to the orange in these pictures. The test mule trucks that are out there now are all just plain non-metallic white.
The Moonshot Green Matte color for the Edition 1 SUV is a matte grey/green paint with a satin clear coat. It’s my favorite for sure. I‘m hoping it will be available on the truck, but I’m thinking it will be SUV only...
