Not exactly the same, but my daughter's been experimenting with the AA test app. This question is tricky:
The correct answer is "Yes" because the light is green for the red car. But you can barely see it on this enlarged screenshot, and you can't see it at all on the phone screen.
My Dad was colour blind and the only way he could tell was the position of the light that was on, and that is what I saw, there was a bright spot at the bottom, but I only looked because of the "fail" otherwise I would have missed it too.
