The following guide is a sub-article of Achieving Color Precision.
Web Browsers
Below is an untagged CSS element on top of a tagged sRGB image. If you see any difference in each color vertically, your browser is currently color managed; otherwise, both reds should look the same, both greens should look the same, and both blues should look the same.
Note
If you have any extensions that mess with how websites are displayed such as Dark Reader, you may need to turn them OFF or disable them for this test.
