TranscriptScreenshot of a pop-up. It reads:

Color Inaccuracies Detected.

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)

If I had to guess, there are various fingerprinting techniques, and some of them use things like drawing on canvases to track you. They are probably referring to that.

Best practice is to have a second browser or profile for specific sites that require you to disable fingerprint protections.
