In most per-site metas common tags have black (and gray) cards; an example is Meta Physics SE.
But there are some sites that have colored common tag cards such as Meta Philosophy SE. And the color of tag cards are exactly the color used in Meta SE.
The deep blue (and light blue) colored tags in those per-site metas have two disadvantages:
When the tags are blue the links are like plain text, but when black we have colored (orange/brown) links (see the above examples and also this question). Of course, in Meta Quantitative Finance SE the no-contrast is between plain text and visited links.
With blue tags the per-site meta looks like a main site.
So please make all of the blue tags black in those per-site metas. All per-site metas are supposed to be universally lookalike.
Other examples include meta sites for Bitcoin SE, Spanish SE, German SE, French SE, etc. Note that in Bitcoin SE, both main and meta sites suffer the issue (There are also some other sites with the main site only that has no contrast between plain text and the links).
