You can do that by some CSS for one page or for the whole wiki. If you want to do it for the whole wiki use this code to change headings and add it to 'Special:CSS': h2, h3, h4 { color: blue !important; } If you want to change the text which appear you can search for the page where you can do that via 'Special:AllMessages' on your wiki.

Hope this helps :)
