CIRCLE WITH A DOT

@harry_wood @emkingma Good feedback. I've updated the intro wording.

@karolherbst they're all in sRGB so HDR _shouldn't_ matter, but having a good display which can represent all of sRGB certainly will matter.

@emkingma you're supposed to click the area where you think the background transitions from one colour to the next. It could be clearer, but I am not sure how best to make it clearer.

@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 @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.

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

@johannes it's a great score! The best I've seen is 0.0018.

@joface this is the one consistent piece of feedback. Maybe we should start a support group.

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

What's My JND?

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

I spent too much time looking at too many colo(u)rs to try and optimise them for csskit. Here are some interesting findings.
