Somehow, the writer for Yahoo Lifestyle managed to see the roofs of the mouths of a “stylish group.” I wonder what a brightly colored palate looks like:
I also wonder why the writer and her editor don’t know that palate refers to the roof of the mouth and palette refers to a selection of colors. (I also wonder why there’s a hyphen following brightly. It’s considered wrong to put a hyphen between an adverb ending in -LY and the word it modifies.)
