Colour Perception

I was also reading recently that the cones in the retina are more sensitive to blue in men and red in women causing a slight perceptual shift in men’s view towards blue/green and in women to red/pink/purple.

I scored 169. Very green apparently. Which is my favourite colour.

Quite old American research I believe. The problem with all eye research is establishing statistical validity. I take part in eye research across the UK both to help test research hypothesis and equipment before trials as well as taking part as a patient. The one consistent thing is that the numbers are horrendously low. Some of the best known claims, which have allegedly confirmed and get great air time, are based on participation of less than 20.

“Your boundary is at hue 176, bluer than 68% of the population. For you, turquoise is green.”

This is interesting to me because, many years ago, I had some perplexing interactions with a client who referred to the “blue elements” on a web page. What “blue elements”? I only saw green, albeit a bluish green. We settled on calling them “teal.”

This is mine.

DG…

I think so far among those posting their “result” the majority "see turquoise as green. It might be interesting to run a poll of forumites, to see how typical we are of the population. Gven the observation about sex maybe a predominance of turquioise is green would be expected, tThen I wnder if age comes into it,… so perhaps as well as the poll requesting whether turquoise is green or blue, also record score, age and sex. And also maybe whether digital or analogue sounds better, in case factors are related!:joy: Oh, and which of quality of source and speakers is more important to you​:rofl:

It looks red, but isn’t. Interesting.

I tried the test earlier this morning and also just now to see whether the result was the same - it was. My boundary is at hue 173 and for me, turquoise is blue.

And yet my results seem to depend on which colour starts the test.

A green start results in turquoise being green, with a reset and a blue start, the opposite outcome.

Power of suggestion at work here, methinks.

I scored 185. Where would Miles Davis score. He said “Blue is green”.

My result:

Your boundary is at hue 176, bluer than 75% of the population. For you, turquoise is green.

but like a few others found, there were a number of colours that were really too close to call. I could have called either way.

But when forced to choose you chose - as we all did.

174 whatever neutral means.

Might try after more wine, the middle hues are very subjective but I did what I do with all tests - gut feel, first instinct.

Interestingly where yesterday turquoise was green to me, with a boundary at 173, testing half an hour a go( Your boundary is at hue 177, bluer than 76% of the population. For you, turquoise is green.), testing just now put me spot on the median: " Your boundary is at hue 174, just like the population median. You’re a true neutral.". But it doesn’t tell me whether I see turquoise as blue or green, so that distinction is highly suspect.

Today I did on iPhone. Yesterday was iPad, repeating iphone just now gave hue 173, greener than 57% of the population, turquoise is blue. Repeating on iPad now I got 177 then 179, turquoise is green.

A double blind study is mutually exclusive to a colour perception test.

185 here, but what does it mean? Is it good, bad or indifferent

I think it means your next car is more likely to be green than blue (or v.v.)

:laughing:

Interesting as this is, it’s not an accepted test for colourblindness. As per my previous post, it’s heavily influenced by environmental factors such as light.

It’s unlikely the light would be exactly the same when you test at various intervals. Your distance from an ipad and an iphone is unlikely to be the same so the ratio of cones to rods in use will differ. The light coming from each device will be different too.

I wasn’t referencing colourblindness tests, just the green/blue boundary test, but yes, exactly, and that was my point - as well as pointless the test is a very vague one without controlled conditions, hence my having turquoise as green in one go, as blue in another, and as neither blue nor green in another (though the latter in between was not a permissible option in thd test!)

It is worth reading the about page, at the start I said it was fun, the author says it is for entertainment only.
I have sent the link to a few more people, the range is now 160 to 184. Interestingly, the person who scored 160 works as a colour mixer/balancer for broadcast TV.

I got to page two and was only offered blue or green when what I could see is turquoise, where the boundaries of turquoise are is a bit vague but that was within them.
