Screenshot 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)

Don’t worry, it’s just fearmongering because the cannot fingerprint your browser and want you to turn of the privacy features.

Hi, developer of the site in question here. That popup exists to warn users that the fingerprinting protections, namely farbling, can cause minor amounts of visual noise to appear in their art. For a pixel art editor, this is not desired, and I received many bug reports about the behaviour, which lead to the popup pictured.

NeedCoolerShoes does not have any fingerprinting in place, and utilises only a privacy friendly analytics tool called counter.dev, where site analytics is public for all to see: https://counter.dev/dashboard.html?user=Moxvallix&token=d7TgWkme7Jo%3D

From I have found on Mozilla Support:

Random data is introduced to background images when the website reads back the image. If a website merely renders data to the background, it will render without alteration. Although typically this does not happen, if the website reads the image data in the background (and potentially displays it to you again), it will have subtle noise that may affect how the image is displayed.

Anti fingerprinting often slightly changes lots of things, including how the browser displays content so that's why.
