Underline and color URL in LuaLaTex

Question

I was wondering how I can underline and color URL in LuaLaTex. I was able to add underline but could not change the URL and the underline to blue. Font is Calibri. Thanks!

% code used in LuaLaTex

\documentclass{article}
\usepackage{fancyhdr,graphicx,xcolor,colortbl}
\usepackage{fontspec}

\setmainfont{Calibri}

\begin{document}

Further information can be found online (\underline {http://findsource.org/})

\end{document}

Answer 1

Try this code

\documentclass{article}
\usepackage{fancyhdr,graphicx,xcolor,colortbl}
\usepackage{fontspec}
\usepackage[colorlinks,urlcolor=blue]{hyperref}

\setmainfont{Calibri}

\begin{document}

Further information can be found online {\color{blue}\underline{\href{http://findsource.org/}{http://findsource.org/}}}

\end{document} 

It uses hyperref package with options colorlinks and urlcolor=blue.

Answer 2

Another try, this time redefining the \urlcommand:

\documentclass{article}
\usepackage{fancyhdr,graphicx,xcolor,colortbl}
\usepackage{fontspec}
\usepackage{hyperref}

\DeclareUrlCommand{\url}{%
    \def\UrlFont{\color{blue}\normalfont}%      Adding a little color 
    \def\UrlLeft##1\UrlRight{\underline{##1}}%  Underlining the url
    }


\setmainfont{Calibri}

\begin{document}

Further information can be found online \url{http://findsource.org/}

\end{document}
