Plugin: Rich Markdown

Hi, sorry for the dumb question. I had to wipe my previous Joplin install and forgot to store my userchrome.css file. I use the Rich Markdown plugin and I can swear I had the URL formatted in the markdwon editor (blue underlined), but after re-installing the plugin and playing with the options I can't manage to get colored URLs (links are clickable using ctrl/click but not colored). Is there some specific css I should use for that? Thanks!
