This is fun! I just played once and got 0.0016, which it says is "absurdly below the theoretical limit"... Okay, tried again and got 0.0034 which is still says is beyond the human limit! I'll have to give this to my mum because we often argue about colours and I suspect she might be a tetrachromat. Both tests on a Pixel 10 btw

#45But now I'm aware of a slightly darker vertical band on my screen, compared to the rest of the display. x_x

#46I can't find it now. Is anyone else aware of what I'm talking about?

#47There was a similar web-game back in the day but for tones. You had to identify which one was higher or lower. Also gave a statistical comparison at the end. Near the end the difference was a couple hertz or something, so next to impossible as well. I can't find it now. Is anyone else aware of what I'm talking about?

#48Earlier quoted context omitted.
It's worse. The code contains a function that, given the target ΔE, generates two colors in floating-point Oklab representation, separated by that distance. But there is no check whether the two generated colors end up rounding to exactly the same one on 8-bit displays. So, I was asked to find a boundary (while the claim was that there were two distinct colors 0.0013 ΔE apart) between RGB(80, 83, 152) and RGB(80, 83,…
I will get around to fixing this. An oversight. Apologies.
