Find the Odd Disk

Would be interesting to get some basic analysis of my results. From a glance it appeared that the ones I missed (6) tended towards red. The low saturation ones and green ones I found to be easiest, but was there any actual significance of the distribution of my errors? Simply too small a set to say?

I got the same number wrong but I've passed every Ishihara test ever thrown at me. I did this test on a cheap mobile that's not calibrated, so it's anyone guess what its gamma and transfer curves are like.

One should only take such tests seriously if one's using a properly calibrated monitor and it's viewed under ideal viewing conditions.

Interesting! All of my misses were blue leaning a bit towards violet.

Same here. The blues/purples were all alike. Reds and greens were easier.
