Well since it's not a direct response advertising campaign, of course no one buys anything "in response to" it.

I did repaint my bedroom with an accent wall that's just about the exact shade of blue that is their 2020 color of the year. Not because Pantone told me to, but maybe because their selection of that color led it to be more prominently placed/advertised when I started picking new paint colors.

Tough to say, and your question is too oversimplistic to make sense as part of the discussion.
