Without being an admin, you can't get a sitewide fix, but you can try experimenting with the CSS at w:c:ididntdoit:Special:MyPage/wikia.css.

Also try adding  after the color name like this: a:link .mw-collapsible-toggle { color: gray !important; }

As far as I know there isn't a template solution (whatever that would be), because the collapsible function is implemented with Javascript.
