Paint Color - Rear Bumper End Cap

[PlatinumPhoenix]

Does anyone know how to find the paint color for a 2018 SCREW rear bumper left end cap? In looking online, it looks like a few different colors were used. The truck is black if that matters and the end cap I’m going to touch up is a very dark metallic gray.
