White on black (footer) and pink/green on blue (header and other parts of the site), for text or other elements, are also problematic and make some parts of the site quite painful to look at.

@TheDJ : Colors is one part of WCAG, I mentioned T201682 that for example there is no alt and some other non-compliance of WCAG that are not related to colors, We can either make this subtask of T201682 or broaden scope of this task to fix all of WCAG issues. Either way is fine for me.

@TheDJ @Ladsgroup On a short look, there are several different topics to tackle, so @Ladsgroup's input is what I had in mind, when first looking at the source code as well. Let's collect them as subtasks, including the current one.

For a range of reasons, like range of available colors, minimum color contrast within colors in such limited palette (think 3:1 contrast requirement of UI components to surrounding text, both in WCAG 2.0 & 2.1) it is not feasible to aim for AAA conformance in product design for most inclusive, biggest possible user group. In our recent Foundation web product launches we were aiming for AA conformance in balancing well-supporting majority of our users while deferring further needs to special software.

Please note that various of our other resources have been finding this balance as well. For example Meta Wiki's top link colors are only conforming to AA (#069 to #fff with 6.25:1).
