Grammaly told me that the "a" in the following sentence is unnecessary and it suggested I remove it:
The surface of the guitar was (a) gleaming white.
Is Grammaly correct? Why or why not?
Note: I searched for "surface was white" and "surface was a gleaming white." I got results in both cases.
Update based on my comment below:
To me, "was gleaming white" sounds like the object is casting a white gleam. "Was a gleaming white" sounds like the object is white, the gleaming type. Am I wrong?
