Color Acuity

This blue dress saga has fascinated/flabbergasted me.

I've always harbor a sneaking suspicion that vast swathes of humanity is colorblind, given some of the pictures and questions you see on fora only reinforces this notion, and this idiotic blue dress thing has brought it to national consciousness apparently. I usually miss this sort of pop culture silliness, but this thing was so pervasive it couldn't be avoided. How anyone thought the dress isn't blue, I will never know, but as over half of the respondents (I'm not sure how this was aggregated honestly, maybe in a Pew survey or something) though it was white, which is stunning. Apparently many people have bigger gaps in their visual acuity than I would have guessed, and the infill processing the brain does to fill it is not terribly accurate.

There is a neat spectral test if anyone want to see how there color perception really is. Score is 0-99, with 0 being perfect.

Re: Color Acuity

I am not sure that gaps in visual acuity account for the data. I definitely saw it as white/tan (gold, I guess) when I first saw it. When I saved it to my computer and saw the thumbnail it was blue/black as clear as day. I scored a 26 on the color test, so I am not that bad at discerning color.

Plus, men have a much higher rate of color blindness---overwhelmingly higher, but women did worse on the "dress test". I think it is clear that the dress thing is not a test of color vision at all.

In my case I looked at the thumbnail image (which definitely appeared blue/black for me) for several seconds and then opened the full photo. At that point I saw only blue/black and could not "trick" my eyes to see the white/gold I originally saw.

Re: Color Acuity

I managed complete ignorance on this dress thing until Doghouse (of course) had to enlighten me.  To my eye, it's obviously blue.

Did anyone else see that they manage to photograph light as a particle and a wave this week?

You can also clearly see there is no magenta

Re: Color Acuity

I'm colourblind and scored 71, I struggle to see the numbers on those Ishihara (dot) tests but it's obvious that the dress is blue and black! Others I know swear it's white and gold.

Re: Color Acuity

I scored 16, but also what may play a factor is the accuracy of your monitor.

Ha ha ha!
No, not an Apple that's my day monitor where I work.
I have a crappy, burn your retinas out, HP flat screen PC at home in the evenings... it's horrendous for colour.
