Theres another work around, use \color{blue} for example:

[[Main Page|
<math>
\color{blue}
x_2^3 = \frac{5}{y^2}
</math>]]

That could probably be worked into a template: [[{{{1}}}|{{#tag:math|\color{blue}{{{2}}}}}]]

removing easy keyword, as doesn't really seem that obvious how to go about fixing it (Assuming it should be fixed). Moving to product mediawiki extensions, component texvc.

This can be done pretty easily with templates, as Bawolff suggests, while it's almost impossible to implement in software.

Perhaps a better thing to do would be to create an extension that allows the creation of math-links {{#mathlink:pagename|x+y\over2}}, or somehow allow <math link="pagename">. That really belongs in extension requests though, and I don't think it's worth it.

It will never be even close to correct as link color depends on skin, user-preference, page-existence, page length and page-visitedness; none of which can be known by the image renderer.
