A good bunch of wikis about video games, especially those on (sigh) Wikia / Fandom, use a dark background. This makes the default black text rendering of Extension:Math basically invisible. But data miners on these game sites do need to talk about math!
The current solution employed on a lot of Wikis is a CSS color invert filter. Doing so makes the black color work, but obviously destroys every other color setting. Their CSS rules can also fail to cover all cases (see example; use inspect element on the block and inline math). In comparison, it would be a lot natural to just inject a \color{White} in front of the formula when rendering.
[A rebuttal would be that a skin change would make the whole thing broken again. Maybe what we need is darkmode/lightmode renderings based on whether the skin says it's dark or light?]
