I already feel dumb, thanks. Part of the problem was that the "click the center" instruction was truncated on my screen. I downsized it to 90% when I showed my wife (I noticed that part of the bottom was chopped off, thus I downsized). She immediately noticed the instructions on top saying "click the center." Literal me, I saw three examples in different colors. I understood I was to choose those colors in succession. #UI #UX
