Why can't they show multiple options similar to the clear type calibration tool in windows? Approximate 6 different colors, user selects the one that matches their eyes best. You could even offer a pro account and send out a camera to monitor to eye calibration postcard that starts with a known input. For sure not impossible given that was 2 minutes of thought, someone closer to the product already has better ideas I'm sure.

So, the real problem here is the "calibrate to your eyes" part. It's true that with a good camera and a professionally calibrated display, you could "copy" anything in the rec2020 color space accurately enough (but not everything!) But our eyes, on the other hand, are really bad at "seeing" color. The same color will look wildly different depending on the colors around it. This isn't something you can calibrate per-person, it'll differ every time. You'd need to read your brainwaves to figure out what you're mind's eye is seeing.

  But your eyes would perceive the color IRL and on the monitor with equivalence so presumably regardless of how other eyes see it, it would be 1:1 copy paste from the camera after calibration. I refuse to believe we have to measure brainwaves to get something close to or indistinguishable from perfect.

Squares A and B are actually the exact same color. I know, it's actually hard to believe—feel free to download the image and sample the colors. :) What "color" does the app copy?

      So the source color is the truth, let's pretend we know it's the paper equivalent of #333. The app captures a color and renders it as #444. The user then says, no wait that's wrong, and the app then provides alternatives that are close, let's say #111, #222, #333, #555, #666. In a perfect world, the user will pic #333 and the app will then know the system introduces saturation error of all three colors by 1 so the next time it will compensate for that. Those errors could come from image processing, light sensor calibration, monitor calibration, backlight color temp, ambient color temp, etc. If the user doesn't pick #333 but instead picks a "wrong" color, that's OK, because the value in the app is rendering the color the user wants and perceives as correct, not what happens to be the truth. The difference between a strict functional requirement "app must render the true color" vs a user req of "I want to take a picture of a color and have the color I see render on my screen."
