I first discovered the gray crewmate by accident. I thought

's color code was 'pink' where it was purple. 'Pink' spawns a gray crewmate, like gray or any other color that isn't cyan, bue, red, yellow, green or purple.
I don't really know who made the first level with him in it. I think it was me, in my crappy-ass internal test Computer Crisis, where I dubbed him 'Vertigo'.
We can all come up with crafty names for him, like Crash Landing's engineer 'Verisix'.
