Screenshot of a pop-up. It reads:

We have detected that your browser may have issues with color accuracy.

You may notice subtle visual noise and incorrect colors appear in your skins.

This issue is usually caused by anti-fingerprinting privacy settings in your browser.

does anyone know what would cause this precisely? why would anti-fingerprinting mess with the colors i use to edit an image in the browser?

i'd be tempted to brush this off as the website being malicious and lying to get me to deactivate fingerprinting protection, but the website is fully open-source and what they describe happened to me on Piskel (a pixel art editor, which would constantly mess up my colors in subtle but annoying ways)

fingerprinting mechanisms use pixel coloring to help fingerprint you. browsers have implementations that fuzz pixel colors to prevent this fingerprinting often in imperceptible manner. Think shifting pixel alpha values by a random +/- 0.3 values; range was arbitrarily chosen for demonstration purposes.

as in, fingerprinting mechanisms use the colors that are in my OS’s color picker? or is it other colors?

Every computer will generate different colors due to driver/os/hardware differences when rendering anything. these differences are often imperceptible to the eye by easily grabbed via browser apis. by randomizing the results just a tad it defeats the trackers.
