Shoreline Mist does not match in the same way as it does on a black Element. There is a good deal of contrast. The thing that I find rather interesting is that the panels look brown-ish on SLM, very coordinated, even though the panels are the same on every color for each trim grouping (DX/EX). Maybe it's the slight metallic look that soaks up and reflects back the color, but they are almost chameleon-like.
Back to your question, though. If you are looking for the most unified, least contrasting combo, then black is your best bet.
