Hey Daniel, just looking at this again. I wonder if some of the inconsistency in results on your test have to do with viewing distance or environment; the standard anomaloscope is more controlled in terms of size of match fields and color temperature context. I suspect this may influence your results significantly.

I got 2 positives, where I could see extremely little difference between the two boxes, and the hue was the very same. So I took a screenshot of the first, and analyzed the colors in Photoshop. They only had 2% difference in brightness, and none in hue or saturation. That is, RGB 166/166/0 vs. 170/170/0. This is definitely a bug.

I think they should match more often. I tried it three times and always only one match. That’s rather confusing, I was thinking I’m doing it wrong.

I am going to assume that it is not a good thing when you are able to match every single color.
