I think your suggestion is very unobtrusive and a great quality of life
improvement! So please go for it!
My only suggestion would be to double check with someone who's familiar
with accessibility with respect to color blindness to find the best
possible default, so that color blind users will not have an even harder
time spotting the prompt.
Cheers,
Dan
