So I'm confused here. I saw the very top part of the image while reading a different post. I then scrolled down and saw it in full after it had reverted to B&W.
1) What has the dot got to do with it? 2) What exactly is the point?
The image repeats. When the bar starts across, stare at the dot. Don't move your eyes. Just stare. Blink if you want to.
When the bar finishes, the images goes black-and-white for several seconds: And when it does, people who've been staring at the dot on the blue+purple image will see it in full colour.
I'm guessing this is the same effect responsible for auras? (Cause that only tends to work well if the person is standing against a white background, and if you're NOT staring directly at where the aura will "appear".)
Expected punch line, expected result. ;-) Though I was suprised that the effect didn't persist longer than it did. Interestingly, the effect does continue to work over multiple viewings and (if one ignores the instructions) in peripheral vision.
Not sure whether having spent so much time looking at C41 negs on an improvised light table has anything to do with my expectations.
Actually, I noticed the colors began to fade near the end of the b&w cycle. The cycle didn't last long enough for them to fade completely, but there was a noticeable difference from beginning to end.
I noticed that if I started focusing on the dot late in the negative cycle (like with only 1 or 2 blocks left on the status bar), the color image faded faster and more noticeably. Likely because the negative image had less time to "burn in" before it switched to b&w.
Tried it again, this time forcing not-blinking, and the effect did last longer; colour seemed to fade gradually starting at the edges and working inward instead of just vanishing. Next try I kept my eyelids open, but failed to entirely counter the small, random eye-twitches the brain really wants to insert to keep the blind spot filled in and whatever other signal-housekeeping effects normally depend on those movements ... and as soon as I was an arc-second or two off the dot, the colours vanished instantly.
So -- that the effect happens: expected. The details of exactly how long and what affects it: rather educational about my nervous system! (But would've been rather less educational if we hadn't compared experiences and you hadn't given me the extra clue.)
Now that is a fun one. I recall seeing a far more basic one years ago about the flag, where you then looked at a wall or something white and you saw that in color. But that is a slick trick here.

Because your brain hates you.
