For those who want to test their perception of colour, I made a little game called "What's My JND"

https://www.keithcirkel.co.uk/whats-my-jnd/?r=ARUjKP__-ve-

What's My JND?

Find your Just Noticeable Difference in colour perception. How small a colour difference can you actually see?

@piggz @hp annoyingly good. The best score I've seen someone get is 0.00018.

@keithamus @piggz I assume that the quality of your monitor also plays a role. Both having a really good and a really bad monitor might help? A really bad one might exaggerate color differences through clipping?

I do have >=150% vision. But I think that doesn't necessarily translate to color vision. But I'm not an expert.

@hp @keithamus I have to wear glasses pretty much all the time, so I guess that doesnt translate to colour perception. My monitor is just a midrange HP laptop, some of them we're really touch and took some pondering time.

@hp @piggz The display you're using definitely matters. I suspect having an old school TN panel and looking it at it from a really sharp angle might distort enough to see the difference, but also those panels could barely show all of sRGB so might not cut it.

@keithamus @piggz well I guess then I'm sorry about my annoyingly good score? 😅

@hp @keithamus How does the number of rounds work, i see people doing different numbers?
Show threadkeithamusMar 10
@piggz @hp There are 6 "rounds"/steps. If you're at round 6 and get one wrong, it'll back off to round 5, to gain confidence that you didn't just fluke it. Each round lowers the threshold. But there's a cap of 40 trials.

@hp @keithamus I got 0.0098, which seems worse than most people's scores. I was using an M1 Macbook Air.

@astrashe @hp @keithamus I wouldn't worry. You also have to factor in that people who have a worse result are also less likely to publicly share it.
Show threadKen ButlerMar 12
@astrashe @hp @keithamus happy to share my 0.0098 also.

I got 0.0029 ... towards the end there seemed a mixture of pretty easy and downright impossible! 😂
