I came back as with a measure of 174 and a label of "true neutral".

However, I know enough about perception to know that this called for some hacking.

So as soon as I saw the second color I realized I needed to look at something else. So each time after choosing and seeing the next color I looked around quite a bit, inside and through the windows at the outside (I happen to be in a Hawaii, so blues and greens are abundant) before choosing and I noticed significantly different color perception after looking around, specifically, I had more confidence in whether it was blue or green.

I can imagine if you just stare at the colors and try to power through, you might get kinda irritated.

I also got 174. I turned the brightness up on my phone (to about 65-70%) before starting, but that was it. No resetting my eyes between colors. Considering I’m red/green colorblind, and certain hues of green I see as gray, I’m pretty shocked by the result. I suspect having a binary choice helped a lot, as once it was no longer something I could consider blue, I’d call it green.
