I did two runs, the first ended at 177 (three more greens than 76%of respondents), the second at 174 (the exact median). I think the methodology is flawed, there’s a little randomness at the threshold so you need to gather more data to be certain of a person’s perception. You’ll see that the same hue can seem bluer when it follows a strong green, or greener when it follows a weak green.

Edit: did a third run, this time staring at a white wall for 5 seconds between each color and responding as quickly as possible. Got 170, way over in the green. A lot of it looked like a pale blue sky.
