Not sure where this should be best posted, but in case anyone wants to see the blue interior (porcelain) option in "real" life, attached are a few photos.
For some reason, Chevy uses computer rendered images and colors in its car build tool so the render vs. real is always off a bit.
The blue interior is nice for a brighter feel. It typically looks gray-is in any light.
Personally, I think the former black/brown interior of 2018 was a bit better but that brown is no longer allowed in the optional choices.
