Red dot vs green dot? Empty Red dot vs green dot?

Many sights are now offered with either red or green dots. I'm in the market for .22lr and would like to make an informed choice.
General consensus suggests green for my older eyes (74) with astigmatism to give sharper image and quicker pick-up. Are there any authoritative articles on the topic?

There is some "color science" in the details of these articles about red vs green LASERs that only sort of applies to a discussion of dots. Other than these shooting magazine articles from 2011, I've found no other references. I'm hoping that crowd sourcing the question here will pique the interest of a shooting-opthomologist to help us out.

This last article is also about LASERs, from a non-shooting source. The eye science is good, though.

Most discussion of dot color in all types of dot sights include anecdotal experiences of the author, sometimes supported by a short reference to eye science by the non-specialist.
I'm hoping there's a professional study lurking in the wild that will miraculously pop up. I can always hope, can't I?

Dr. Joe Logar presented a paper on red lasers and green lasers at the last NRA Annual Meeting in Indianapolis (Riflleman, Mar 2020, pg 24). I submitted a question to him through the NRA.org website to see what he might contribute to the discussion of dot color. I'll post his response if I get one.
