"This shouldn't be possible. I'm not saying that you cheated, but not not saying that."

0.0011. The quote seems a bit hyperbolic. There were maybe 2-3 that I didn't see and missed. 1-2 that I didn't hit perfectly but close enough. Display probably affects results (but didn't change any settings for this). I have a Dell IPS. I also moved my head around a bit, felt natural while trying to discern the colors.

I do have a good vision (including color). Reminds me of the other color-game where you order some colored boxes to form a spectrum.

Edit: just tried hard mode and got 0.0084. Missed maybe 3 that I couldn't see. Usually some magenta or blue colored. Grey and red / brown seem to be the easiest.

In the early 00's, I used two pro grade NEC flat panel monitors... they weighed a lot... my desk at that time had a permanent bow in the middle. It was around 2008 or so when I'd moved them a few times in a year and a half and decided to switch to flat panels... It became very clear to me around that time, that most people really didn't care about color accuracy in designs. Couldn't tell you how often I'd get "it doesn't look like our printed logo" only to adjust their monitor settings and voiala. Even then.

LCD flat panels are much easier to move around without killing your back. OLED is pretty amazing, but I've got to turn my brighness down a bit to make it tolerable... and I just about have to use dark mode. But there aren't many options in the 45" 3440x1440 display range, which is where I'm most comfortable today.

I can see what they mean about .02 though. If I weren’t specifically looking for difference that’s where the colors become less noticeable.

There's was 2 or 3 where i had no idea, guessed and was a way off.

There's was 1 where i did a hail Mary and got it. It was interesting how some even towards the end were really obvious and others were really subtle - I'd say I did better with purple tones and worst with the blue / greys.

I need a better display for sure :)

I do work with colors pretty much every day as a UI engineer
