Where are my dyschromatic brothers? We're supposed to be about 7% of American males, not sure about proportion in other parts of the world. Interesting, I wonder if there are fewer of us here, on a photography forum - limited color discrimination could naturally select against this hobby. It seems very dependent on time of day and ambient light. I scored 205 last night, improved to 58 today. Wondering about an implicit learning effect on this too.
Anyone else who scored relatively poorly, don't feel bad. It's a variation that is so common it's generally considered normal. They may not let us fly planes, but I'm not sure what their cut-offs are. What is also interesting is that in spite of the dismal score on this, day to day life is generally not affected. I had no idea I had reduced color discrimination until I saw Ishihara plates for the first time.
Right here. I got a 143. Ouch.
