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.
