No, I see the boxes as tan and light blue. But I see the dress as Blue and black.The eye can be tricked in all sorts of ways (or rather, our perceptions can be). Michael shows how they can be tricked with his shaded boxes above. But then goes on to say that we see a green green ball as the same colour both inside and outside.
I don't think we do. But we don't realise that we are seeing a different colour - our brain compensates.
When I was a kid, I used to watch TV on the floor, laying on my side, with my head resting on my arm. My head was at 90 degrees to the TV. I did this so often that my brain compensated and processed the image so that it appeared aligned to the angle of my head.
There is a pretty famous experiment where people wore mirrors and walked about. Their brains compensated. Incredible stuff is imaging and the brain. |

I have, however, just noticed something while scrolling through this thread.
If, when I first see the image at the head of the page, it is on the lightened version, I see a white and gold dress. Then the darkened version appears and I see a black and blue dress. The next time the lightened image appears, I see a washed out black and blue dress.
Can people really see the darkened image and only see a white and gold dress in THAT image?
Our processing of images is incredible

That's my point when I say human beings aren't light meters and
colorimeters. We don't see color in terms of absolute values. It's always
relative to the various light sources.

I did find it interesting that I saw the
picture on my phone in one room and it was
blue and black. The next time I saw the
same picture in a different room, it was
white and gold.

I've seen it on the same device at different times of day, in different lighting conditions, and it's flipped.

It always looks black and blue to me.

Apparently there's a biological component: the number of cones in your eye.It will affect how many colors you see here:
For the record, I see 37 colors in the linked image. And see light blue and gold on the dress. :)
True to the article, I have no yellow clothes.

That's a strange test - it depends where I look on the screen as to how much differentiation / how many colours I can see.
The dark blue, dark green and yellow segments can appear as one or many colours depending on where I look.
I wonder if my eye is being fooled because all the colours are the same width so it is bringing in false splits.
I'd like to see that spectrum with different widths of colour so you can't look at a width and think 'that's supposed to be three different colours there'.

"You see less than 20 color nuances: you are a dichromats, like dogs, which means you have 2 types of cones only. You are likely to wear black, beige, and blue. 25% of the population is dichromat."I wear black, beige and blue, and I see 35 colors. Just how "scientific" is this "test"?

It's probably a decent test with accurate color reproduction in lighting levels fixed to a standard. Which is not what anyone would be getting on the internet. I notice I see one more color on my phone, which has the contrast set much higher than my monitor. So as we're getting it, it's probably ball-park, but not super-accurate.
As far as it's fashion predictions, that's probably arm-wavy at best. I mean, what if you like irritating colors?
Edited to add: One other thing, is those are probably supposed to be violet on the left, but are actually purple. The color gamut of a computer screen only goes up to blue. Get out a black light to see the difference. Those mostly put out UV-A, but the visible portion is violet.

Not a dress, but the appearance of highlights on black is a topic of interest here.

has anyone ever read/done the Max Luscher (sp?) Color Test - the book was required reading 1st year in college. I liked it, found the reasoning sound enough for my unscientific mind, and thought my results were accurate. i wonder if they still print it? anyone know?
