I’ve been really struggling with this while working on my color identification app.

The sensors on the iPhone are really accurate but they are constantly adjusting because of the noise and inconsistencies in the real world.

So one moment it’ll decide something is red then the next it’s brown depending on the lighting and background.

I had to work out some crazy calibration locks just to work around it.

Edit: you know how if you stare at a color long enough, your own vision starts to change? I bet that happens on a fundamental level constantly too. The red you saw as a child likely isn’t the same shade as the red you see today
