Looks like this. Doesn't look dirty or murky.
I just found the same thing on my 2015. Had a low coolant light but can’t find any leaks. It was 1.5 quarts low. But on top of that I noticed it was a orange/gold/brown color just like in your pic.

This gives me some comfort, that someone else has the same but is definitely confusing. Anyone have any ideas yet?
