<p>A musician balancing a cello case, two Buddhist monks in saffron robes, and a group of stockbrokers in crisp,charcoal gray suitsget on at Wall Street.
I thought the answer would be "charcoal, gray suits" but instead the correct answer is no change. Can anyone explain this to me?</p>
<p>charcoal gray is one color?</p>
<p>^ That’s how I see it. Charcoal and gray are not separately describing the suit; they are acting as a single description. </p>
<p>Notice that “crisp” is a description separate from “charcoal gray.” In that case, a comma is needed for separation.</p>
