<p>Thanks for the answer ^-^ </p>

<p>It is actually possible without javascript, see http://community.wikia.com/wiki/Thread:1153156 . </p>

<p>SU appears to use a similar solution to TableWiz, with nested templates. That border color can't use accent-color, or avoid nesting templates...unless they use a div container around the infobox with the correctly colored border. I think that's not as good as the JS - the infobox is no longer a child element of the article content. But a native solution would be better. </p>

<p>Oh, interesting. So I simply need to do this? </p><p>Template:Test/Infobox </p>

<infobox accent-color-source="BGColor" theme-source="BorderColor">

<p>Template:Test </p>

{{Test/Infobox
|BGColor     = {{{BGColor|}}}
|BorderColor = {{{BorderColor|{{{BGColor|}}}}}}
}}

<p>Yep. It worked just like it should. Thank you so much, Anon ;D </p><p>The templates: </p>

<p>Well, if you really want to use such a  hack, then you don't even need a second template, something like this should suit your purposes: </p>

<infobox accent-color-source="BGColor" theme-source="BGColor" accent-color-text-source="FontColor">

<p>Well, we already have the code that turns theme source into backgrounds and borders at the same time. I wanted the ability to have different background and border. The only issue was that the template is already used on ~350 pages, and changing javascript and the template without making a second template would change the appearance of all pages. </p>

<p>The Javascript hack still isn't needed. It is trivial to write some css classes that account for the most common classes used in a wiki. as it is highly unlikely that these templates use 300 different Hex colors. </p><p>Anyway, as long as the solution works for your wiki, it doesn't matter that much. </p>

<p>They do ;D </p><p>Thanks again anyway. </p>

<p>In addition to a wish to avoid nested templates, a div container (if it uses class or style) around the infobox instantly makes even a PI non-portable. We're looking into a native solution to this issue. </p>
