Overview
To check the color contrast between foreground and background of the texts
It checks the color contrast between the foreground and background of the elements that are in the page according to the WCAG 2.2. It evaluates the contrast on all elements of the page considering their computed style for the color and background-color CSS properties. In case of these colors are defined with RGBA values, it also considers the opacity to deduce the real color that finally is show. It can simulate color blindness and evaluate the contrast for the simulations. By this way, developers can see how the pages look for colorblind users. The tool also includes two fields in which the colors can be introduced manually to be tested. It also allows to pick the color directly from the documents. Finally, it auto-refreshes when DOM of the page changes (addition or removing elements), but if the page has many changes, this behavior can be de-activated.

Haven't had any major issues with it. Works well for what it is and can quickly verify contrast on page across multiple visual deficiencies.

Does not really work well, in some cases it detects the wrong colors for for- and background. forground: #ffffff background: #ffffff But on page it is: forground: #ffffff background: rgba(25, 145, 238, 0.8) It also does not respect text-shadows which improve the readability, which is confirmed by people with very bad eyesight.

Hi, thank you for sharing your opinion. To improve the extension, could you please share the page in which the problem with wrong color identification is happening? By this way I could check what could be the reason for that and fix it. Regarding the text-shadows, to be hones, it is not a property that it checks. It basically tries to identify the computed color, the computed background, and if there are elements with opacity, tries to estimate the color with that information, but it never considered the text-shadows. I will start thinking about it and try to find a way to analyze it. I guess it will be a bit tricky, specially because the shadow can varies depending on the distance and also the direction. I am not sure if that case will be feasible. Thank you very much, and again, if you can provide the scenario in which it apparently fails it would be very useful to improve it.

Love it! Would be great if you could add support for APCA and Oklch colors as well.
