Remember "The Dress"?

The one that looked blue and black to some people (including me), and white and gold to others, that is: Well, this Guardian article is about colour perception, and a test you can do. I see green more than 75% of the gen. pub., apparently.

I see blue more than 75% of the population.

My result was "Your boundary is at hue 174, greener than 55% of the population. For you, turquoise  is blue."

ETA - looking at the graduations on either side of the line that it drew, I wonder if I saw them on a different screen with different light whether my answers would be different.

[Nearly Sane]

My result was "Your boundary is at hue 174, greener than 55% of the population. For you, turquoise  is blue."

Mine was "Your boundary is at hue 177, greener than 75% of the population. For you, turquoise  is blue."

So a relatively small move in terms of hue has a big effect at this level

Your boundary is at hue 195, bluer than 99% of the population. For you, turquoise  is green.

[Roses]

"Your boundary is at hue 190, bluer than 98% of the population. For you, turquoise  is green."

177. 78% Green

Funny, when I first saw the final picture I thought "my boundary is exactly average right on the border between blue and green" and then I realised, that's the point. Different people see the border in different places. Duh!

My result was: Your boundary is at hue 177, bluer than 78% of the population. For you, turquoise  is green.

Mine was at the same point. 

Earlier this year I had cataract surgery - with a gap of four weeks between my left and right eyes. Following the operation on my left eye (the first) I was able to consider the extent to which my aging lens had denatured the colour of the world around me. White (through my new lens) looked little like the experience I called white through my (so far unoperated) right eye.

I wonder, therefore, if some of the differences reported here are due to the effects of aging?

Your boundary is at hue 174, just like the population median. You're a true neutral.

Did it twice and got different results. Both times when the graph came up I felt the boundary was in the wrong place!
