By default the NPS question is structured as a table, with each number in its own cell.
What you'll need to do is to hide the numbers, creater a row at the top, which spans all the cells and then add the colour gradient.

Would you be able to share the Javascript that would enable this? Very interesting...

AdamK12 I won't be sharing the code, because it's just aesthetics, but here's a demo, if you'd like to see the end result.

Trying to impact the background color of each of the individual boxes in the NPS question.
Thanks in advance
