I was reading a New Yorker article regarding Donald Trump's inauguration ([A Dark Inaugural By Benjamin Wallace-Wells][1]) and I came across this sentence at the very end: 

>Today, Melania Trump’s coat was pale blue and Michelle Obama’s was maroon, and that seemed to capture the day: patriotic, yes, but **a few shades off**. 

What does "*a few shades off*" mean here? Is it pointing to the somber colors of their outfits or perhaps to the overcast, dark tone of Trump's message to the American public? 

Checked the Internet but couldn't find an answer.
